I started off with bittersweet parting from all of my family and friends as I left for the summer, and then as soon as I woke up Sunday (May 15th) the hurricane of pure chaos began. And honestly, it is amazing. There is so much to learn here. As a previously inept coder I have already had to struggle through opening GUIs and ssh-ing and scp-ing and it has been an uphill battle. On top of that we got to PHENIX and I immediately was told "Watch these graphs." So this week has been a week of 2am and 6am runs out to a building full of hissing pipes and pressure gauges, and hours of clicking through the same 60 pages of graphs. But oh man has it been a great start to the summer.   -Matthew Kimball     FROM HALEY STIEN: Hello, Dango, for the first time!  This week has been eat, sleep, work, repeat it seems. Being nocturnal is  kind of cool, but I look forward to the end of these night shifts so that I don’t have to sleep my days away. Learning how to work Voltage Control was fairly easy.. Until every server decided to die one after another. While everything was working correctly, however, I kept myself busy trying to upload my profile picture to the server. I feel like that might’ve been the most difficult thing I’ve done so far, which it probably should not have been. Other than that, my days consist of Netflix and naps. Thank you, Cecily, for bringing The Office and How to Train Your Dragon into my life. Also, the Carlos stuffed crust pizza definitely lived up to my expectations. I have never been full after just one slice of pizza until now.   See ya, Haley Stien  FROM CECILY TOWELL: Dearest Dango, It has been too long my old friend. We arrived at BNL on Sunday night. On Monday, we worked on getting badges for the young ones (Haley and Matt) and got DANGO compiled by Haley Stien   2 |  P a g e✉hxs12a@acu.edu caught up on everyone’s training. Starting at midnight that night we began our midnight-8am shift that will continue until Tuesday. I am the DAQ operator, which means I am responsible for stopping and starting each run and reinitializing all of the granules in between to make sure all of the electronics are communicating nicely. Basically I have the most important and difficult job, but I have thus far handled it with aplomb. This is not a particularly enjoyable shift as we now sleep all day and are up all night, but we are enduring this predicament with grace (and with the help of caffeine and Chinese food).  Until next time. Cecily Towell  FROM DR. RUSTY TOWELL: Hello DANGO,   It is so exciting to be part of DANGO for its 22nd year.  I remember when DANGO was created so long ago when email was still something new.  Dr. Sadler had a great idea to help everyone working in the ACU Nuclear Physics Research Group to stay connected.  Of course you couldn’t read DANGO on your smart phone and we didn’t have a picture of the week contest, but we did share what we were working on with each other. The BNL branch of our group arrived on Long Island last Sunday.  Matt, Haley, Cecily, and I spent Monday getting our training done and started taking shifts at midnight.  I’ll admit that being on shift from midnight until 8am is not the funnest time to be working, but at least we have good company.  We did get on a historic shift.  We have the last shift on PHENIX for collisions of d+Au at full energy.  It is sad on the one hand that this is the last year for PHENIX.  However, with the number of problems and alarms we’ve been having this week, I’m not sure the detector has much life left in it.   I hope everyone’s summer is off to an excellent start.  Grace and Peace, Rusty    FROM ARIC TATE: Hi Everyone, I am currently at Los Alamos working for the Neutron Induced Fission Fragment Tracking Experiment (NIFFTE). I am doing analysis work on the alpha rate for two separate triggers of the NIFFTE time projection chamber. So far I have calculated an alpha rate for the cathode trigger and macro-pulse trigger using the data available to me. Since this calculation was not conclusive, I am now performing a statistical test to determine whether or not the two sets of data come from the same distribution. The particular test I am using DANGO compiled by Haley Stien   3 |  P a g e✉hxs12a@acu.edu requires a large amount of permutations which is time consuming and might kill my Mac at any time. I also signed up for, studied for, and took the GRE this week. Do not do this.  -Aric Tate    FROM ZHAOJIA XI: Hello everyone, This is Zhaojia Xi. I am working at SeaQuest/E906 experiment in Fermi national accelerator laboratory this summer. After Joshua drove Paul and I for 18 hours, we arrived safely at Fermilab Sunday evening. We started working on Monday and we got our photo IDs, temporary dosimetry badges and got our computer accounts settled down.  We learned how to use mySQL and ROOT. Dr. I and Dr. D gave us several lectures to help us understand more about SeaQuest experiment. We also went to a talk at Thursday afternoon, the speaker from Ohio state university talked about Nb3Sn conductors for future accelerator magnets. Although I personally do not understand all the details, I have a deeper understanding about how to improve conductors. It has been a great week so far, I am really excited about this summer.  See Y’all next week, Zhaojia Xi   FROM CALEB HICKS: This week started with learning about SeaQuest and Fermilab in general. We got ID badges, radiation badges, and registered for mailing lists. We relied entirely upon Paul to make sure we didn't get lost, and as a result we consistently got lost until we stopped trusting Paul. The actual work we got done this week was mostly helping with odd jobs; lifting and moving high voltage power supplies, fixing serial cables, and so on. We also spent a good deal of time reviewing old pdf's from the SeaQuest document database to get more familiar with some of the past projects. We don't have internet yet at the apartment, and social order is rapidly breaking down. Hopefully the internet router will be delivered today so we can stop living like savages.  -Caleb Hicks  FROM JOSHUA MARTINEZ: The first two days or so I dedicated mostly to memorizing the area due to the fact I am the only one with a car and Paul Carstens is not a reliable navigator even though he's been here before (he got us lost a lot). Apartment was chaos due to being 2 beds short but that problem is mostly solved and we still do not have internet at our apartment so what little sanity we had is practically gone. On the educational side we did fix a serial cable that its mapping was unknown, so we undergrads did map and repair the cable to DANGO compiled by Haley Stien   4 |  P a g e✉hxs12a@acu.edu allow laptops to talk to a power supply system. We have also got to a talk about how to improve particle accelerators using Nb3Sn cables. Other than that we are still learning the process of how SeaQuest runs so we can start shifts soon.   Sincerely, Joshua Daniel Martinez  FROM PAUL CARSTENS: As with most first weeks, it's been a bit slow. First day I renewed my ID and computing account and got my radiation badge. Turns out the whole SeaQuest building requires radiation badges, so that means there's, like, at least a 40% chance of one of the interns getting superpowers at some point. On an unrelated side note, left and right are really hard to tell apart, so if any non-specific person happened to get them mixed up and gives incorrect directions it's totally not a big deal. Over the next four days we've been working on some high voltage control crates. It's mostly been inserting and removing power supplies or dragging old HV crates out of storage. A more interesting task was repairing an HV serial cable. The noobies tested the pins while I soldered them in place. Beyond that we had several physics lectures from Dr D and Dr I. The week was fairly uneventful.  -Paul Carstens   FROM SHON WATSON: Dear DANGO, This first week has been fine. I arrived at Fermilab on Sunday. I've been working primarily on the HV power supply issues. Yesterday, we had some success communicating with some of the HV controller modules. Unfortunately, they don't seem to be working as well today.  -Shon Watson  FROM DR. MIKE DAUGHERITY: DANGO, I'm always grateful when everyone arrives in one piece.  We've made a lot of progress in jumping through the right hoops in the right order to get ready for shifts next week.  We even got an impromptu lesson on radiation safety when a rad tech discovered something radioactive sitting out unlabeled on the table.    Really ready for the weekend, Dr. D  FROM DR. DONALD ISENHOWER: To all in Research Land, This week was spent in getting students started and trying to get myself started on a task I only found out about a day before I left.  They asked if I had students who I could assign to work on it, which with five here at FNAL I do, but there is this little comment at the beginning of the repair document in bold-DANGO compiled by Haley Stien   5 |  P a g e✉hxs12a@acu.edu face warning about working on the power supplies to be extremely careful as touching the wrong part results in “DEATH ON CONTACT.”  The problem is that Fermilab no longer has anybody left who knows how to repair our high voltage power supplies.  We had been OK we a few spares, but a lightning strike took away that aspect and we have one system now running on a different HV system until I can get enough of the LeCroy 1440 HV system modules repaired to where we have a full system and a spare to put it back in.  Paul has the most electronics background, so he is the most likely choice to be my helper.  If I had known earlier that I was going to be assigned to working on repairing these modules I would have packed different things as these are old designs and require some of my really old stuff I chose to leave behind in Abilene.   Otherwise things went as typical for the first week.  The data rate we are running at is what our experiment was designed for, which is great.  We have some problems, such as getting low on spares on some modules for our DAQ system, but that’s not unusual when you’ve been running for three years.  Our run is extended to July 30, so we are running about 3 weeks longer than planned.  That’s good since the accelerator and detector are running well.  Next week I serve as Run Coordinator, which just means I’m in charge of making sure everything gets done.  We also start taking shifts on SeaQuest, which will be just the start of a large number of shifts. Now if we can just get better sleeping surfaces for all four guys in their apartment, we will be sure to have rested students, OR, we can keep two of them on shift at any given time and then they can sleep in shifts on the real beds!  -Dr. I.

When I touched them they exploded into hundreds of tiny yellow spiders who couldn't wait for us to get home.  In unrelated news I may have superpowers now.”    Haley: “Art.”    DANGO compiled by Haley Stien   7 |  P a g e✉hxs12a@acu.edu Dr. Towell: “PHENIX All-Star Crew”

We started off with only a few shifts left (the last of which a replacement was late to but oh  well). We've gotten to relax and do some more fun things around Long Island. After   Dr. Towell left we went to go see a pretty great aquarium. We've also gotten to go around and have lots of coffee and find the sketchiest coffee shop ever as well as go to Montauk Lighthouse. We also went to the beach which was pretty great.  Have a good one, Matthew Kimball  FROM HALEY STIEN: Dear Dango,  Our days off have been so great that I barely remember the couple of night EDITOR’S NOTE: Thank you, snapchat filters  DANGO compiled by Haley Stien   2 | P a g e  ✉hxs12a@acu.edu shifts from earlier this week. Adjusting to being awake during the day was a struggle, and waking up at 1AM to make a sandwich was also weird for me. However, we managed to get back to normal (with the help of caffeine and freezing waves at the beach). We decided that today and tomorrow will be work days, which includes collectively writing a paper about Dr. Towell’s NEXT Lab and setting up our office. The last few days, however, consisted of a few beaches, a lighthouse, aquarium, and cute coffee shops. Don’t listen to Matthew- that coffee shop was not sketchy. It was just closed and in a weird alley behind some shops.. Anyways, it’s been fun riding around in a lovely, giant, blue van and finding cool places to explore. We have dubbed Tend Coffee our favorite coffee place because it is cute and the people are friendly.   -Haley  FROM CECILY TOWELL: Aloha Dango, Tuesday was our last day on the midnight to 8 AM shift, and was also the day that our fearless leader abandoned us. However he shall be back on Wednesday with reinforcements (AKA my mom and siblings). Since then, we have been exploring the island. We've gone to an aquarium, the cutest light house ever and the beach. We also have discovered our new favorite coffee shop, chosen as the best for its cuteness of course. While the boss is away, we have been tasked with setting up the office and writing a paper on the NEXT Lab at ACU (if you don't know what that is, visit www.acunextlab.org and look up Rusty Towell TED talk- you're welcome). We have also begun plotting to capture the groundhog that lives near us. We shall be victorious.   -Cecily  FROM DR. RUSTY TOWELL: Hello Dango, This week started the same way last week ended.  More owl shifts on PHENIX.  We finished taking 62 GeV data and then started taking data at even lower energies.  After working until 8AM on Tuesday, I caught a flight back to Abilene. On Friday we will start the drive back to NY.    Happy Memorial Day to all, Rusty    FROM ARIC TATE: Hello Everyone, This was my last week at LANL. The highlight was a 4.5 hour mandatory safety meeting for all of LANSCE to discuss a series of inexcusable accidents. Much was said and even more was learned at DANGO compiled by Haley Stien   3 | P a g e  ✉hxs12a@acu.edu this gathering. I am a better person for having been in attendance. I also went to a graduate student's talk on QGP and PHENIX. I am still not entirely sure what he was doing at LANL. I will now be heading towards New York by way of Texas.  -Aric Tate    FROM ZHAOJIA XI: Hello everyone, This week has been great. I will work on sqerp (SeaQuest Event Reconstruction Program) this summer and I have already read lots of sqerp documents. Dr. D helped me get the sqerp program and code to plot different things. On Thursday, Dr. David Christian and I had a control access. We went downstairs and replaced a QIE board. Also Dr. I is fixing several high voltage circuit boards right now, he gave me a short lecture about electric circuit. It is always nice to learn and understand physics in real life. I will do day shifts this weekend (Saturday and Sunday), so I hope everything goes well.  Peace out, Zhaojia(TIffany) Xi     FROM CALEB HICKS: This week was mostly low key. I went in for normal work on Monday, but the council decided that it would be good to have two people on the night shift instead of one, so I took Tuesday to flip my schedule and spent the rest of the week on the owl shift. Since I naturally go nocturnal on weekends anyway, and shift is fairly relaxed, this week has been pretty nice. Also, internet has arrived so the apartment is less reminiscent of Lord of the Flies.  -Caleb Hicks  FROM JOSHUA MARTINEZ: What's sup DANGO, This week was rather interesting, as we introduced a new member into our rather small apartment unexpectedly. Having to rush around and set everything up for him to live here was the task for the weekend. Monday and Tuesday consisted of setting up the new arrival to have access to Fermilab as well as receiving training to be able to take shifts. Wednesday we my first shift and it was rather stressful because it wasn't a smooth run. Thursday was by far the smoothest run I have had, only having to stop once for a minor change. Then today (Friday) I did not have a single complete run. Everything went wrong from the main injector to HV power supplies. It was rather interesting in that I learned how to fix what feels like a lot of different problems that SeaQuest could have. All in DANGO compiled by Haley Stien   4 | P a g e  ✉hxs12a@acu.edu all I feel as this week was a very productive week.   Sincerely, Joshua Daniel Martinez  FROM PAUL CARSTENS: Greetings and salutations! It's been another, expectedly slow week as I've been working the night shift since Monday. The beam's been very quiet; there have only been a couple of issues so far, none of which took much more than a reboot to solve. After the first few days alone I began seeing Caleb around the control room, though I suspect he's naught more than a vivid hallucination. The week of shifts isn't over yet, however, so Hallucination-Caleb and I still have another few days till we rejoin diurnal society.  -Paul Carstens  FROM REUBEN BYRD: Dangoo, it's good to be back! I got to Batavia on Saturday, did all my training on Sunday, and was at work Monday. Apparently I missed the week where my apartment had no internet, but I can live with that. Monday and Tuesday were kind of introductory days for me since I'm new to Fermilab, but since Wednesday Josh and I have been on day shift here. Beam was down most of Friday, so it was really exciting. It's been good, though, since I'm still getting used to how things are here as opposed to at Brookhaven. I think we may go downtown this weekend, we'll see!   Peace, Reuben  FROM SHON WATSON: Dear DANGO, This week, I continued to work with the Lecroy 1440 high voltage power supplies.  I spent more time working on sqerp (a SeaQuest track finding and fitting program). I found it interesting that sqerp uses the MINUIT minimization library for fitting the tracks.  I hope my past experiences with MINUIT will come in handy.  Today, I just finished re-upping my controlled access training.  I have also been trying to learn the updated shifting procedures in preparation for my swing shifts next week.  -Shon Watson  FROM DR. MIKE DAUGHERITY: Dearest DANGO, SQERP!   One of the big problems with students is that when they just start to get really interesting and useful, then they leave.  SeaQuest has lost several grad students and postdocs, leaving a major crisis of exciting opportunities for us to work on.  One of these is the SeaQuest Event Reconstruction Program, or DANGO compiled by Haley Stien   5 | P a g e  ✉hxs12a@acu.edu SQERP.  Shon, Zhaojia, and I have starting sqerping along with some other grad students.  Once we figure out the code we'll have about seven months of data to reconstruct.  It is going to be a great summer.    -Dr. D  FROM DR. DONALD ISENHOWER: Dear Hard working students, This week has been spent working on LeCroy power supplies and controllers, while giving lessons.  Sometimes these lessons have been on these same things as to how if you don’t read the schematics of the device it is easy to set yourself up to die.  You pick up this nice drawing, and it innocently identifies itself in the lower right hand corner of the blueprint as “LeCroy +5.3V Power Supply.”  You work though the circuit (unpowered) and trace out the 5.3 V power circuit, then notice this section that just doesn’t seem necessary.  You look a little closer and discover its output is 350V DC sitting in the middle of the circuit diagram with nothing to call attention to itself.  After this you check the +15V and -15V supplies and discover all three have this circuit buried in the middle of the circuit diagram.  Each of them also have capacitors on them that make each one lethal.  Oh the fun of working on electronics designed by people who happen to leave off small “footnotes!” On the “helping students” front, Cindy found mattresses and box springs for the two poor students who have been sleeping on air mattresses.  We don’t have bed frames, but hey, you can’t get everything!  Cindy and I have found a longterm housing arrangement that the lab has set up with Homewood Suites.  The nice thing is that it avoids taxes and comes with a shuttle that will take Cindy up to 5 miles in any direction she want to go.  It’s not too far from the lab and is cheaper than anything I could work out on my own.  So we’ll have a place to live after Beth D. gets up here and we have to leave the lab apartment. Now it’s back to figuring out why a controller I was working on yesterday was talking to me then, but is refusing today. Dr, I. from the exciting land of the buffalo, geese, foxes, deer, coyotes, pheasants, squirrels, snakes, and many other critters running around outside our area.  -Dr. I.

Aric and I worked on our projects as much as we could without Mickey until he finished shift on Thursday and we got a significant amount done without and with his help. The electronics that were my and Haley's task to work on have all been tested and now all that is left to do is to work through the graphs to figure out the specifics for each piece of the circuit. I'm excited for July 4th on Monday and another week after that.   Talk to you later DANGO, Matthew Kimball DANGO compiled by Haley Stien   2 | P a g e  ✉hxs12a@acu.edu FROM ARIC TATE: Hello everyone, mRPC progress this week was negligible. After removing the mRPC and testing the pre-amps last week we returned the mRPC to its vessel and reattached all HV, LV, signal, and gas. Unfortunately, when I arrived on Monday the gas had ceased flowing. We should have a new tank of R-134a waiting for us on Tuesday, which means we should be able to ramp up HVWednesday and begin seeing signals. With our might leaders (Rusty and Mickey) back, we will surely be able to resolve any signal issues and be able to move on to a detector with more gaps. Also, much progress was made in the electronics study.  -Aric  FROM HALEY STIEN: Hey Dango,  I had the last week off and spent my time exploring Long Island and NYC with my mom. It was fun, but now I have nothing to report about work. This is also why Dango is a little late this week!  Sorry… Not sorry, Haley     FROM VICENTE ROJAS: I spent the first half of this past week making sure that the hydraulics calculations for the Brady wastewater plant were correct. I am still waiting for my boss Josh to look at them. The second half of the week was spent writing a design report for a simple wastewater treatment project. Kubota Tractor Corporation (KTC) is currently building their new headquarters in Grapevine, TX. They asked eHT to design a simple wastewater treatment facility within their property. KTC intends to treat their own wastewater and reuse it for irrigation. It is a great initiative. Not only will they save a lot of money, but this will help the city reduce the amount of flow that goes to their wastewater collection system.   Happy 4th of July!  Vicente    FROM ZHAOJIA XI: Kon'nichiwa Dango, This week I spent most time working on my code. The code runs pretty DANGO compiled by Haley Stien   3 | P a g e  ✉hxs12a@acu.edu well right now, Andrew is asking me to access and print out more data and I am working on it. On Thursday we went to hear a talk about the engineering of particle detectors. Speaker talked a lot about cosmology which really grabbed my attention. On the same day, we found out that Keithley system has been down since the late April. Dr. I went downstairs and power cycled the system. Also during the control access, I saw shed skin for the first time and I am proud to say that I overcame one of my biggest fears.   Ready for the long weekend, Zhaojia(Tiffany) Xi  FROM CALEB HICKS: <Generic Greeting>, This week I helped Dr. I a bit with the cosmic ray detector and made sure that I understand what everything is doing and how it all works. I also spent a lot of time looking over code to make the dark photon MC interface with the tracking software, but Dr. D finished a lot of it while he was on swing and I wasn't able to help much. Other than that it’s been a slow week. Still waiting to get a project, though Reuben and Paul have their so it shouldn't be too long I hope.   <Generic Send-off>, Caleb Hicks  FROM JOSHUA MARTINEZ: Wassup DANGO,      This week was rather relaxing due to the fact I had Monday and Wednesday off to fix my sleeping schedule. Tuesday I had a rather easy swing shift and it was rather relaxing. Thursday I learned I am going to be helping with the cosmic tests of scintillators for dark photon triggers. That made me actually pretty excited knowing that I have a primary project to be working on. Friday we attempted to do some actual building of the cosmic test stand but ran into the problem of not having anything to cut wood with. The main issue is I need to cut a rectangle out of the middle of a 3/4 inch sheet of plywood. To do that, I am going to need a Jigsaw, which we just don't happen to have. So that pretty much shot our progress down on that until we can acquire one. Hopefully Tuesday I can start cutting and building this project. Happy 4th of July, DANGO.  Sincerely, Joshua Daniel Martinez  FROM PAUL CARSTENS: Salutations! Things have been accomplished this week! I finished up the PT kick study on mc drell-yan data and calculated the magnet pt kick settings that give the best results. The values are considerably different than what was previously recommended, but these new values give better results on the mc data. I don't know what to make of it, but since I've started DANGO compiled by Haley Stien   4 | P a g e  ✉hxs12a@acu.edu work on the cosmic ray test stand the jTracker baton has been passed to Reuben.  On that note, josh and I have now started working on the cosmic test stand to test the SiPMs. Unfortunately, the light tight box we have won’t fit the test hodoscopes and the SiPMs' scintillators so we'll need to cut a hole in the side and extend it. We've got the extension all planned and now we just need to cut the wood, build it, and test it for light leaks.   Still alive,  Paul Carstens  FROM REUBEN BYRD: Hi Dango, Early this week Paul and I finished the macro for graphing the alignment of the detectors. The problem now is that the table we are pulling geometry files from is in a different database than the run data we want to sqerp, and the permissions are denied for editing with the login that we use. Long story short, I'm waiting for things in the database to be updated. Some of us are also working on building a new light-tight box for some efficiency studies for scintillators that will be used for the dark photon search. In other news, I'm leaving this Friday and will be gone all of next week, I'm working at a summer camp in Wisconsin with some of my family.  Tschuss, Reuben  FROM DR. MIKE DAUGHERITY: DANGOers, I've been mostly working evening and weekend shifts this week, but in the meantime I've had a few pleasant findings this week. It is always fun to run across several things done by previous ACU students.  We've used a beam monitor, a light-proof box for testing scintillators, and the super fancy digital multimeter used to read out temperature, pressure and humidity in the experimental hall.  I crossed paths with the last one when we realized it wasn't being displayed correctly in the database.  Eventually I found a subtle bug that broke the web page after we reached our 1,000,000th beam spill and the extra digit broke things.  It felt kind of like reliving Y2K all over again.  We will have a similar problem when we reach a million runs, so if we keep going at the current rate I calculate that will be in January 2197. By far the most interesting thing to happen this week was during Wednesday's controlled access while the beam was down for maintenance (something about a 600 gallon/day water leak).  The Los Alamos group had left a computer and VME crate near the target just to see how much radiation damage they can take before they stop working (spoiler alert: not much).  While they were bringing up the now-defunct computer they noticed something unusual hanging above the door. They crept in for a closer look and found a 4 foot long snake skin in DANGO compiled by Haley Stien   5 | P a g e  ✉hxs12a@acu.edu SeaQuest.  That means our experiment actually has a GIANT RADIOACTIVE SNAKE slithering around it.  How many people get to have that at work? Sometimes I just really love my job.  Stay Classy, -Dr D  FROM DR. DONALD ISENHOWER: Report from Dr. I. from Fermilab: This week at Fermilab has been spent continuing developing the muon setup for testing the SiPM test for the extruded scintillators that will be used for the dark photon trigger.  I also have been working on final ideas of what can be done on testing the LeCroy High Voltage systems power supplies.  I have concluded that I will do debugging that can be done without 208 AC power on them on the bench, mostly due to all the rules that the lab has if I do that, so I will test the parts that run off the low voltage regulators on the test bench and then attach wires to test points and put it into the crate to check things so that one can’t touch the deadly parts of the circuits. I’ve also been trying to finish edits of my parts of a paper that describes the SeaQuest paper that is being submitted to the Nuclear Instruments and Methods (NIM) journal very soon.  I also completed my abstract for the DNP meeting in the Fall, which is the one all of you students will be expected to submit posters to via the CEU program.  It is being held in Vancouver, Canada. Larry arrives this weekend and we will have a birthday party on Sunday at his wife’s parents’ home in Naperville.  Cindy and I celebrated our 37th wedding anniversary on Thursday the 30th.  We tried out a new Italian restaurant on the Fox River in Batavia.  Keep on working! Dr. I.   In Other News..

In order to get the high voltage things that we wanted out of the racks on the very top of the PHENIX detectors we first had to remove them from their respective racks and the wires strung under the floor made that harder than it should have been. After that we had the task of getting them from the very top to ground level. Originally we were going to put them back in the racks and let the workers crane the racks out and we'd just get the pieces then. That changed though and yesterday we adventures with getting all of the various electronics down. Everything worked out though and I think they've already been cleared (? That might be something else).  DANGO compiled by Haley Stien   2 | P a g e  ✉hxs12a@acu.edu Have a good one DANGO, Matthew Kimball  FROM CECILY TOWELL: Gesundheit Dango, This week has just been non-stop excitement. We spent some time in the lab taking apart and putting together mRPCs. We were given a super fun glass mRPC to take apart that has lots of broken and burned pieces, so Haley and I have been cleaning that too but we have to wait for more glass before we can try to put it back together. We've also been running out to PHENIX about every day to take apart, clean, and box up pieces of PHENIX to send back to ACU and to UIUC. We have spent a good deal of time discussing CEU poster topics and then writing up the abstracts. My topic is the mylar mRPCs that we've been building, so it'll probably be the coolest poster of them all.   Gotta catch 'em all, Cecily   FROM HALEY STIEN: Dangoooo,  This week we started to discuss CEU abstracts and who was doing which topic. I still had basically no idea what was going to be my topic, but after thinking over all possible options with Dr. Towell and Mickey, I finally know what I’m doing! That was definitely a relief. Aside from abstract writing, we started going out to PHENIX to take apart, clean, and ship off various parts. We also made some mRPC progress and have begun testing the Mylar mRPC in the cosmic ray stand. We also worked on meticulously cleaning the super thin pieces of glass from the glass mRPC.. Fun stuff. I can’t believe there’s less than two weeks left now!!  Yours truly, Haley  FROM ARIC TATE: Hello everyone, This week we focused on retrieving what was ours (and UIUC's) from the remains of PHENIX. Results were mostly successful, as some of the HV had previously been sent to CERN. Besides the equipment located in the IR, we were also able to salvage a lot of gas flow pieces and parts. The racks were sitting in the parking lot in front of the RPC tent, our place of residence in years past, when we found them. Now we just have to wait for some activation checks and then decide how to deliver everything to its correct destination. Also, gas is again flowing through the mRPC chamber. Initial results after turning up the HV do not look promising. We need to do some tests on the anti-static mylar to determine if it is worth pursuing further.  FROM DR. TOWELL: Hello Dango, This week started with the reminder from Dr. D that we only had two DANGO compiled by Haley Stien   3 | P a g e  ✉hxs12a@acu.edu weeks to submit CEU abstracts.  That was a clear indication that our summer work is coming to an end soon.  So this week we’ve focused on what we’ve done, what we’d hoped to accomplish, and perhaps most concerning, what needs to be done before we depart BNL. In addition to abstract planning, writing, reading, and editing, we’ve also started tying up loose ends here at BNL.  We’ve finally started testing the mylar mRPC in the cosmic stand after waiting for new gas bottle so arrive.  Initial results are looking very mixed.  It is holding HV while drawing very little current which is great, but the signals coming out aren’t very clean.  The cosmic rate is very low, so we are continuing to collect data. We’ve also started gathering the RPC electronics, gas distribution systems, and power supplies to return to ACU and UIUC.  It turns out that between the assembly tent, IR, RHIC tunnel, and storage cabinet, we have stuff spread out all over BNL.   Lots more to do.  Only two more weeks at BNL.  Grace and Peace, Rusty     FROM VICENTE ROJAS: Given the urgent need for a new water treatment plant (WTP) at Cisco, TX, this week we focused on getting the project off the ground. As I mentioned a few weeks ago, the Cisco WTP was flooded under 20-25 ft of water. Several engineers and I were assigned to design and size different components of the WTP. I was assigned to size clarifiers and an equalization (EQ) basin. The purpose of the clarifier tanks is to allow for the solids in the raw water coming from the Cisco Lake to settle out before they go into the filtration system. Followed by this, the water then enters the EQ basin, which acts as a buffer. This buffer, between the clarifiers and the filtration process, helps the filtration process get the right amount of water. If an EQ basin was not built, the filtration system will experience drastic changes in flow, which would shorten its lifetime.  On Tuesday, we celebrated David Todd’s birthday. He is one of the engineers that founded eHT. In the middle of the party, Jordan assigned me another project. Between the other intern and I, we had to look over 600 pages of blueprints from the Hamby wastewater treatment plant in Abilene and make sure that the markups matched the actual drawings. I finished DANGO compiled by Haley Stien   4 | P a g e  ✉hxs12a@acu.edu looking at the last drawing on Friday. I did not want to start next week with a pile of drawings on my desk.  In my time off, I have been taking an online speech class and hanging out with the Korean and Japanese students who are at ACU for a summer camp.   -Vicente      FROM CALEB HICKS: <Generic Greeting>, This week I've done a lot of error troubleshooting and dealing with computer issues. I was working on compiling a root macro for a while, then started working on modifying the GMC program used for the Monte Carlo simulations at SeaQuest. Because the Dark Photon MC program isn't interfacing well with any tracking program, I edited the working MC program so I can edit the Z-vertex of the dimuons and see what a dark photon decay would look like in the detector (especially how changing the vertex affects the probability that we will detect it). I spent a few days trying to figure out why it was giving me far fewer events than I asked for (5-10%), but then found out that it's working as intended. So I spent Friday running a lot of simulations to get the events I need but mostly I spent Friday trying to fix everything and eventually, after about 7 hours of the combined work of all the experts, it seems to have fixed itself or something; honestly I have no idea. Good week, though I'm concerned because I'm on shift Saturday and Sunday and won't have experts if the same problems re-emerge.  <Generic Send-off>, Caleb Hicks  FROM ZHAOJIA XI: Nong hao Dango, This week I was mainly improving my code. We use hodoscope efficiency data to calculate trigger efficiency. Tuesday we went to an undergraduate lecture which talked a lot about dark matter. On Thursday we attended another undergraduate lecture. That was the best LIGO speech I have ever been to. The speaker helped me understand gravitational waves a lot better. I left Batavia Friday afternoon, now I am staying at downtown Chicago with my mother's best friend.   Time flies, Zhaojia(Tiffany) Xi   FROM JOSHUA MARTINEZ: Wassup DANGO, This week I made a lot of progress on the light tight box extension, and hopefully I can finish it today. It ended up with me having to build a lot more things DANGO compiled by Haley Stien   5 | P a g e  ✉hxs12a@acu.edu that I initially thought I was going to which stressed me out slightly but handled it pretty well. Something fun to mention, Wednesday I got to crawl under the floor of the E906 building and pull out a lot of, from what I understand, valuable cables. I think some PhD told me it was work about $3,000-$5,000 worth of cables. Maybe Dr. Isenhower will submit a picture of if for the vote next week. I can say I am looking forward to this tour of NuMI Underground today at 1:00pm and hopefully, I can finish this box by then.   Until Next Time, Joshua Daniel Martinez  FROM PAUL CARSTENS: Greetings! While measuring cosmic ray flux I noticed some disturbing fluctuations in my hodoscope readings. They had wild (~30%) disagreements on cosmic ray flux. After a bit of panic I learned that the method I had been using to determine their voltage settings wasn't conclusive so I redid the study with significantly more data points. While trying to set the threshold voltages for these new settings I found even more fluctuations. After another, larger bit of panic and some weeping and gnashing of teeth I've concluded that the test hodoscopes are very sensitive to physical agitation and that whenever I had touched the source to them for my tests the contact had thrown the measurements off. But now I've almost got the settings that Josh needs for his project. In other news, it turns out Monte-Carlo data is easier to use than real data. Shocker! I've been continuing my magnet transverse momentum kick study on real data and not having the MC truth as a load-stone has been making it very difficult to discern what the optimal settings are. At first I tried using mass, z-vertex, and momentum, but all those did was tell us what we'd expect the magnets to do. I then tried using reduced chi squared and the number of events and tracks, but those proved unhelpful. So now I'll be going back to mass, but this time I'll be using significantly more events to try to get a clean J/Psi peak to use. I suspect that it will help but still leave some ambiguity. If so I'll try discriminating it with number of events and or reduced chi squared.  Once more unto the breach,  Paul Carstens  FROM REUBEN BYRD: Been catching ‘em all.  FROM DR. MIKE DAUGHERITY:  Spent my week helping Reuben.  FROM DR. ISENHOWER: The Isenhower Report: Well I missed last week because things were going nuts at the end of the week.  I’m eeking in this week as things are doing slightly crazy thing week as DANGO compiled by Haley Stien   6 | P a g e  ✉hxs12a@acu.edu well.  My success is that I have now brought back to life 7 LeCroy 1445 High Voltage crate controllers.  Not bad as FNAL hasn’t been able to repair one since last summer.  I plan on giving them 3 back for good will as I’m happy with 4 spares.  I have not been successful in fixing the 1441 Low voltage supplies though.  That’s what was happening last Friday and Saturday.  I thought I had on fixed as I found a bad +12V voltage regulator, replaced it, and then discovered that whatever the problem was, it blew out 12 V voltage regulators.  Then this week while trying to probe for voltages on different places on the board I accidentally touch the can on a transistor that had it’s outside metal can connected to it’s collector, which was hooked up to -120V, and that did a number on the rest of the circuit.  So now I don’t know what the situation is with the LV supply.  Very Frustrating! This weekend I am visiting my two daughters in Brighton, MI.  Anna and her Adam live there as he preaches at Brighton.  My youngest daughter, Roberta,  has traveled up with her boyfriend to visit her so we get to see both of them and see this boy who obviously is at a serious point of possibly being added to our family if she is bringing him to meet her sister for approval.  :-) If is crazy to think that next week will be my last with students.  I leave on the 23rd for a vacation on the Canadian Rocky Mountaineer Railroad.  It is what I am using my prize money from the APS award I received last year to help pay for.  I will be back for a few days in August (5th-8th) to finish up and then go see my grandson here in MI one more time before heading back to ACU to get ready for teaching Astronomy and EP I.   Of course I will be reviewing student abstracts over the next week.  That’s all rom Dr. I.   In Other News..

Since then we’ve been learning about what we’ll be doing for the rest of the summer, which is mainly building and testing different prototype mRPCs (multi Gap Resistive Plate Chambers). These are PID (particle identification) detectors that are instrumental in experiments like PHENIX. The goal is to get these guys down to a timing resolution of 10ps so that they can be put into a PHENIX upgrade like super PHENIX. On Wednesday and Thursday we mostly sat through lectures about what we’re doing and the big physics questions DANGO compiled by Haley Stien   2 | P a g e  ✉hxs12a@acu.edu we’ll be addressing. Today I started taking apart a failed mRPC prototype, and will now work on reassembling it with different materials. As to my side project, I did catch a groundhog, though my colleagues do not support that claim. Perhaps it would be more accurate to say that I tripped over it in the midst of pursuit. Regardless, progress has been made.   Voy a coger la marmot, Cecily   FROM HALEY STIEN: Dearest Dango,  This week we began our work with Mickey Chiu, a scientist here at BNL. The first couple of days consisted of lectures and introducing us to the kind of work we will be doing. Matthew and I will be studying the electronics part of the whole mRPC project while Cecily and Aric will be building and testing an mRPC that uses Mylar instead of glass. However, it looks like Matt and I’s project will have to wait until next week because we start another week of shifts on Tuesday. Aside from work, not much going on here! We planned on going to the beach today, but the wind was so crazy that we gave up on that idea and have had a relaxing evening watching the Office instead. In other news, we are making more and more progress on our groundhog hunt and have also taken up golf as a pastime.  -Haley  FROM MATTHEW KIMBALL: Hey-o DANGO, This last week has been a good one, we finished off our 8am to 12pm shift and I can honestly say that I preferred the 12am to 8am shift. After that we started working with Mickey and I have been assigned the summer project of "electronics". Along with Haley, we will be responsible for measuring the bandwidth of all the electronics Mickey or Aric or Cecily want to put into the mRPCs in order to minimize interference with the data collected. This job has been relatively easy and boring so far (I've just been plugging and chugging with a sine wave generator and an oscilloscope) but I'm looking forward to working on this over the summer.  Later DANGO, Matthew Kimball  FROM ARIC TATE: Hello Everyone, This week I drove to Brookhaven and began my work with the others who just finished a shift. We have just begun working with mRPCs (multi-gap resistive plate chambers) and have also started a bandwidth study to help determine if the readout electronics are adequate. My summer's work looks to be centered around the building and testing of a mylar mRPC as well as some analysis of data collected using a 3D printed mRPC from DANGO compiled by Haley Stien   3 | P a g e  ✉hxs12a@acu.edu UIUC (University of Illinois Urbana-Champaign).  - Aric  FROM DR. RUSTY TOWELL: Hello Dango, This week started and (hopefully) will end with me at BNL. On Monday and Tuesday I attended the Spin Workshop that is part of the RHIC/AGS Users Meeting and worked on my talk for the conference I’m traveling home from now.  On Wednesday I traveled to Nashville and attended the first day of the Christian Scholars Conference at Lipscomb University.  On Thursday I gave my talk titled "Advancing Molten Salt Reactor Technology to meet the Needs of the World”.  Unlike most conferences I attend, this conference has a very very broad range of talks, however there was a nice series of talks delivered by and for STEM folks.  It was neat to hear about how other Christian universities were conducting engineering focused mission trips to third world countries.  I hope this is something we can start at ACU soon.  My talk focused on the new NEXT lab at ACU.  If you don’t know what that is, check out the website:  acunextlab.org.  Grace and Peace, Rusty   FROM VICENTE ROJAS: There is no precedent as to what happened in Cisco, TX last week. You probably heard about the highway washing away, but the aftermath of the water treatment plant (WTP) was shocking. The WTP flooded at least 6 ft. It was a complete loss. The city did not have running water for hours. Given that the City of Cisco is one of many eHT’s clients, my bosses had to rush there to try to fix the problem. On Wednesday, I got the opportunity to visit what use to be the WTP with a couple of eHT engineers. As we pulled up to the site, I was surprised to see all structures still standing. I was surprised when I saw algae hanging from utility poles that carry electricity wires. That is how high the water level was at one point!  Days prior to the flood, the rain caused Lake Cisco to exceed its 100% capacity. The WTP was located in between the dam and Highway 6. Once the water started overflowing the dam, Highway 6 blocked its natural course. The water started to accumulate in this area and eventually flooded the WTP. Once the water finally made its way across the highway and the WTP dried out, dead fish were found all over the facility. DANGO compiled by Haley Stien   4 | P a g e  ✉hxs12a@acu.edu In order to get water back into the city’s distribution system, a mobile WTP trailer was hired. This unit can supply one million gallons per day (mgd). Several adjustments are being made to the unit to increase its water supply. Even though the immediate water needs of the City of Cisco are being met, it has been declared under an emergency state. It is ironic how the excess water/rain can leave a city without water.  I have spent the rest of the week at the office reading reports, collaborating with other engineers, and eating donuts. One of the perks of working at eHT is that they have donuts every Friday. I have bonded with Daniel, the other intern from Texas Tech, pretty good. We have been going to ACU’s recreational center to play basketball and soccer a couple of times. Lastly, I successfully completed my driver’s test and got my license.   -Vicente    FROM ZHAOJIA XI: Hello Dango, I am still working on hodoscope efficiency this week and I am getting a lot better at understanding Fortran code. My supervisor Dr. Chen left on Tuesday morning, so I asked him a lot of questions about this project on Monday before he left. I finished programming on Wednesday, Dr. Chen and I keep communicating through emails. He gave me some very nice suggestions about how to improve my code yesterday.  Now I am doing my best to write better code, add more functions and more arrays. On Thursday, everyone was invited to our spokesperson Paul Reimer's house. The cookout was great, we all had a very good time there. We got to know our spokesperson better and had a chance to pet his giant dog (Becky). This week has been fun and eventful. I feel blessed to work here.  Have a great summer, Zhaojia(Tiffany) Xi  FROM CALEB HICKS: <Generic Salutation>, This week I started working on the dark photons research. I'm helping to convert the Monte Carlo data into a format that our tracking software can understand. Mostly I've just been looking over lots of code and writing down the data members for all the different classes. I was hoping that they would line up nicely and I could just copy them over one-to-one, but it looks like I won't be able to do that. Other than that I haven't really done much this week, just the usual learning about hardware and nuclear physics.   <Generic Send-off>, Caleb Hicks  DANGO compiled by Haley Stien   5 | P a g e  ✉hxs12a@acu.edu FROM JOSHUA MARTINEZ: Wassup DANGO, This week was far more eventful (and tiring) than last week. Monday I was thrown in head first into learning programming which is a lot to learn in order to be able to do what I'm supposed to. So I have been trying to catch up on programming even though I've only owned my own computer for almost two weeks. Tuesday was the beginning of the Undergraduate talks here at Fermilab so we attend that as I continued my endeavor to absorb all the knowledge of programming I need. Wednesday I was on shift and had had some slight trouble but was handled properly. Thursday was exciting as I finally found out what my project is going to be specifically. Friday (today) we had a meeting to establish who is taking what shifts and made a schedule for ourselves the next two weeks. All in all this week was rather fun and I look forward to the weeks to come.   Sincerely, Joshua Daniel Martinez  FROM PAUL CARSTENS: Greetings and salutations! The summer is starting to pick up speed now that we've been assigned our projects. I still don't have one cohesive task, but I do know that I'll be working on jTracker. This week Reuben and I have been working on some mass comparison plots using jTracker on montecarlo data to find the optimal settings for the fmag and kmag pt kicks. In other news the undergrad lectures have started up. So every Tuesday and Thursday we attend those. We've attended the first two lectures thus far. Lecture one was an introduction to fermi lab given by the director and the second lecture was a quantitative look at accelerator physics.  My week's been cut short a day as my family has arrived for a vacation, so for my long weekend I'll be in Chicago visiting the attractions and eating pizza.  Ready for deep dish, Paul Carstens  FROM REUBEN BYRD: Hey dango, This week we started working on our respective projects. I ran sqerp on a Monte Carlo reconstruction while adjusting the fmag and kmag "ptkick" constants. This is all in the goal to find the problem with the mass offset in the dimuons. Paul has been running similar tests as well. This week Fermilab started an undergrad lecture series, se we attended two lectures this week. One was a general lecture about Fermilab, but the second one was really interesting I thought. It talked about the physics of building and running accelerators. On Monday we'll continue with the models until we find the optimal ptkick settings for the correct mass. DANGO compiled by Haley Stien   6 | P a g e  ✉hxs12a@acu.edu  'til next week, Reuben  FROM DR. MIKE DAUGHERITY: Greetings DANGOers, You probably knew that a septum is the thin wall of tissue that separates your nostrils.  You probably didn't know that a septum is also a term for beam splitters.  (If the beam is coming out your nostrils and your nose was sitting at high voltage, then the septum would be a row of grounded wires.)  Fermilab septum MI-52b is part of the contraption that sends beam from the Main Injector to SeaQuest, and it happened to break while I was on shift over the weekend.    We also had a fun issue with a faulty flammable gas detector causing miscommunication with safety inspectors.  Lupe is still working hard.  On top of data taking we've all be gaining XP in our analysis projects. But most importantly, my family arrived on Wednesday.  Beth now has to get a chest xray before every flight—it’s just part of living with a serious lung disease.  We were all pretty nervous about the trip but everything was fine.  Life will be much better now that they are here.    Farewell, Dr. D  FROM DR. DONALD ISENHOWER: Dango Land report from Dr. I. the elder, The LeCroy High Voltage system I put in last week is still working fine, so that is a relief.  But now I am trying to get more than just one complete spare system.  The low voltage module is becoming more enigmatic the more I work on it.  I at first thought it was so big because it put out a large current.  I then realized it was putting out at most 5 Amps or so, which made me think that they were just worried about it being extremely stable.  Now after studying the thing more carefully I have realized that the maximum current it’s output transistors can drive is about 250 mA and the final output is controlled by a Regulating Pulse Width Modulator which usually has a larger ripple voltage on it, so I trying to figure out why the company built such a complicated +/-15 and +5 supply and then generated the final output this way.  So this remains my main challenge here at FNAL. Yesterday I saw my wife off to Brighton, MI which is where my son-in-law preaches, but primarily, it is where we have our other grandson (1 year old).  So I will be on my own for two weeks.  We also moved out of the FNAL apartment and into an extended stay hotel that has an arrangement with Fermilab since Beth Daugherity arrived.  It’s not cheap, but cheaper that renting an apartment and then leaving it empty for the bulk of the summer! On Monday at our collaboration meeting I will be giving the overview and status of the SeaQuest experiment, so I DANGO compiled by Haley Stien   7 | P a g e  ✉hxs12a@acu.edu shall go back to preparing that talk!  Dr. I.  In Other News.. A note from our Engineering Librarian: DANGO Now on the Digital Commons! Miss an issue of DANGO? Not to worry, the library is now archiving issues of DANGO on their Digital Commons. I will be uploading them as they come out, and will also be uploading the E&P Newsletter starting this upcoming term! http://digitalcommons.acu.edu/dango/            -Your Librarian, Jasmine Hoover  Highlighting young PHENIXians: “The success of PHENIX now and in the future critically depends on the hard work of the young people in the collaboration.  We are continuing the monthly tradition of recognizing the work of these PHENIXians. This month, we highlight the work of  Dmitry Kotov  (PNPI and PSPbPU) and Cecily Towell (Abilene Christian University). The web pages (linked below) highlight their work, their backgrounds, and even some of their non-physics interests.

Over the week we rebuilt a mRPC, which took us awhile since different problems with electronics and such kept coming up. However we’re working on putting it into a cosmic ray test stand and gas is flowing so we should be able to start taking data soon to see how well this new design works. The little ones (Haley and Matt) are on the 4pm-midnight shift, so I haven’t gotten to see them much which is pretty lame. I probably will not be sending a Dango for the next few weeks since my family and I will be going to Honduras early  Monday morning for two weeks. It’s a great trip where we get to help build houses, host a few VBS’s, hand out food and all that good stuff. Please pray for Haley as she endeavors to survive without me.   Adios por ahora, Cecily Towell   DANGO compiled by Haley Stien   2 | P a g e  ✉hxs12a@acu.edu FROM HALEY STIEN: Hey Dangoers,  This week I’ve just been on the Evening shift (4pm-12am), which has been mostly uneventful as we have only had a couple days when we took data. I look forward to Tuesday so that I can finally go back to a normal schedule, but by that time most of the Towells will already be in Honduras.. BUMMER. They are my main source of entertainment/socialization, so I will impatiently await their return. Aside from work, we went to the beach on Saturday, which is always fun. I insisted that I didn’t need sunscreen, but my sunburn has proven otherwise. One day I’ll learn.  Adios, Haley  FROM MATTHEW KIMBALL: Hey DANGO, This week has been pretty good. We worked for a few days in Mickey's lab and then Haley and myself went back on shift for the evening shift (4pm to 12am). While working in Mickey's lab we made much more progress along the lines of finding out the responsiveness of the Oscilloscope we will be using to test the rest of the electronics. And shift. Well. Shift has been boring. We've had one day of actual data taking and other than that it's been transitions or maintenance that has kept us just treading water.  Talk to you later, Matthew Kimball  FROM ARIC TATE: Hello Everyone, This week turned out to be very productive. We were able to come together as a team to accomplish the tasks laid before us, even when the odds were stacked against us. Our leaders really stepped up and put in performances that will not soon be forgotten. By a strange coincidence the physics research could be described the same way. An anti-static mylar mRPC was built and is now holding high voltage. The previous sentence does not adequately capture the drama that is building a particle detector, but unless you were there I won't be able to convince you otherwise (We aren't all witnesses). I will forge onward next week as most of my team leaves me for Honduras. The primary goal is to read out signals and possibly begin building a 48 gap anti-static mylar mRPC. Go Cavs.  -Aric  FROM DR. RUSTY TOWELL: Hello DANGO! Today at BNL we celebrated the 16th and final EOR (End of Run) Party.  There were lots of good folks present and of course loads of grilled meats.  Earlier this summer, PHENIX held a 25th anniversary dinner.  While neither ACU nor I were founding members, I’ve DANGO compiled by Haley Stien   3 | P a g e  ✉hxs12a@acu.edu been a member of PHENIX for 17 years and ACU has been a member institution for 15 years.  During this time PHENIX has produced lots of interesting results and trained several generations of students.   This week Aric, Cecily, and I have spent much of our time in the TOF lab assembling and testing a new prototype mPRC.  The gaps in this multi-gap RPC are made with sheets of mylar spaced by fishing line.  This makes for extremely thin gas gaps.  We got it assembled and installed in the gas vessel yesterday afternoon and flowed gas overnight.  Today we were able to raise the HV on it unto 14,000 volts.  It appears that we are seeing some real cosmic signals out of it.  Next week we plan to take some longer cosmic runs with it to confirm its performance.   Next week I’ll be out of the country on a mission trip to Honduras with 3 of my children.  We hope to build several homes, a church, host a VBS and share the love of Christ with the people of Honduras.  We welcome your prayers that we can be used by God in meaningful ways.    Grace and Peace, Rusty    FROM VICENTE ROJAS: “Engineering degrees should have more psychology classes. There’s a formula for almost everything, except for dealing with people”, said Josh, one of my eHT’s bosses, while coming back from a design meeting with the representatives of the City of Brady, TX (City). This was my week’s favorite quote. True enough, once you come out of college, you will hardly ever have to derive a formula. Depending on the field of engineering that you choose, you will have to deal with clients, engineers, operators, manufacturers, among other people. Dealing with people’s egos and interests is a challenging aspect of engineering. This Thursday (June 16), I got to attend a meeting between eHT and the City’s mayor, project manager, city attorney, water plant manager, among other people. I quickly realize that the agenda served no purpose. Questions got asked left and right, ranging from the legal agreements to the specific piping in a street intersection. Regardless of how unorganized this meeting was, many important details were discussed and agreed upon. Surely, there will be another meeting because Josh didn't even get to talk about his proposed improvements to the water treatment plant.  One of the major projects that I worked on this week had to do with the improvements done to a water disinfection system at Midland’s, TX water purification plant. I spent three straight days digging DANGO compiled by Haley Stien   4 | P a g e  ✉hxs12a@acu.edu up information, understanding complex plans, sketching possible alternatives, and finding the right manufacturers for the different pieces. I finally went to my boss Jordan to give him an update on what I had done. Before I even got to talk to him, he told me that there had been a change of plans and that they were going to redo the whole system a different way. “That’s engineering for you Vicente”, he said. Hopefully, some of the work I did will give me adequate experience for this new plan. As an engineer, it is our job to adapt and adjust ourselves to ever-changing decisions.  Unrelated to work, on Thursday night, I went to the Movies on the Hill event and watched Zootopia. I believe it is a perfect depiction of the problems and struggles that American society faces today. Watch it. I recommended it.  -Vicente    FROM ZHAOJIA XI: Hello everyone, This week has been crazy. Monday and Tuesday we had SeaQuest collaboration meeting from 8am to 6pm. I have learned so much about SeaQuest during these two days. It was nice to hear people's presentations from all different positions. Wednesday and Thursday we had Fermilab annual users meeting. Every experiment in the Fermilab and DOE gave talks about their plans, results and etc. I have understood dark matter and cosmology better than last year. I am and will take swing shift through this whole weekend. Hope every equipment here will work well.  Peace out, Zhaojia Xi  FROM CALEB HICKS: <Generic Salutation>, This week I'm on owl shift so there really isn't anything exciting happening. Shifts have been nice and quiet except for yesterday when everything went wrong. Josh's car managed to lock itself while I was getting my radiation badge, so I spent half of the shift calling locksmiths. Got the car unlocked finally, and less than 30 minutes later one of the important computers crashed and so all the alarms started screaming at me. Finally got everything working again, only to have one of the ROCs crash. So overall a calm week with only one small apocalypse.  <Generic Send-off>, Caleb Hicks  FROM JOSHUA MARTINEZ: Wassup DANGO, This week was rather exhausting, more so than previous weeks. Monday and Tuesday consisted of collaboration meetings which consisted solely of DANGO compiled by Haley Stien   5 | P a g e  ✉hxs12a@acu.edu presentation giving details about the experiment. In all rights it should be very detailed but it was just mentally exhausting attempted to keep up with all of the information. I was very thankful for the breaks and lunch to let my brain process everything that just happened. Wednesday and Thursday was the Fermilab Users Meeting where I learned about all the other experiments going on at Fermilab. This information was not as intense as the collaboration meeting but was still rather difficult to understand some of the talks given. Either way it was rather interesting when my brain wasn't melting out my ears from the overload of information. Today we are having another SQERP meeting I believe and hopefully I can get some work done on my project.   Until next time, Joshua Daniel Martinez  FROM PAUL CARSTENS: Greetings! It's been a busy week! There hasn't been much working, but we've been in talks and conferences non-stop since the week started. Monday and Tuesday we had the SeaQuest collaboration meeting to attend. The talks were quite technical in nature so I could only qualitatively follow along. Wednesday and Thursday we had the user's meeting to occupy us. These talks were still more technical than I could easily understand. However, since they were aimed at an audience that lacked the intimate knowledge of the experiments that was expected in the collaboration meeting the talks were generally more accessible. Now that it's Friday and the conferences are over we can get back to work. Today I'll be finishing up the study on how the FMag and KMag pt kicks affect jTracker in monte-carlo j/psi data.  -Paul  FROM REUBEN BYRD: Hi Dango, This week was a little hectic for all of us, I think. We had to take the owl and swing shift this whole week, plus there was the collaboration meeting Monday and Tuesday and the User's meeting Wednesday and Thursday. Also, the undergrad lectures are still going on, so there was that as well. I worked the swing shift the majority of this week so, sadly,  I missed a lot of the talks. One cool thing I got to do was help get the "baseline" measurements from some SiPMs with Ming. He put three fairly close to the beamline to see how (and if) the radiation will affect the optimal operating voltage. What we did was measure that before it has been exposed to anything.   'Til next week, Reuben     DANGO compiled by Haley Stien   6 | P a g e  ✉hxs12a@acu.edu FROM SHON WATSON: Dear Dango, My last week at Fermilab was busy with SeaQuest swing shifts.  I have been working back in Abilene for the past two weeks.  Early this week, I remotely attended most of the SeaQuest collaboration meeting. I have been working on the Niffte online software. A while back, the Niffte offline framework's build system was transitioned from Autotools to CMake.  The online software still uses Autotools.  I started trying to migrate the online software to CMake too, but it has been more work than I expected.  -Shon  FROM DR. MIKE DAUGHERITY: <DANGO!>  We started the week with the two-day SeaQuest Collaboration Meeting.  We also had the two-day New Perspectives Conference for young researchers to network and present their work.  After that we had the two-day 49th Annual Fermilab User's Meeting. By Thursday evening I felt like we had worked a six day week.  Our brains are full with lots of new ideas to try.  </DANGO!>  -Dr. D  FROM DR. DONALD ISENHOWER: To Dangoland, This week started with our SeaQuest collaboration meeting.  My talk was to give an overview of how everything on the experiment was running.  So I had to go and gather information on how our data acquisition system was running, which modules in it had failed in the last few months, how many spares we had of which part, discuss the hodoscopes, discuss the work I have been doing on the high voltage systems and what that likely meant for the rest of the run, and so on for everything else in the experiment and detector.   It was fun getting some of that information from people about the subsystems they are responsible for.  The meeting went well and preparations for the next two parts, a dark photon search and polarized Drell-Yan were discussed over the rest of the two days.  Of the other major thing discussed were results coming out a preparation of a paper being submitted to Nature. The next two days were the Fermilab Users Meeting.  Various talks were given during that time on lots of different topics.  Hopefully some of them get mentioned by the other students who got a chance to attend (some were on shift).   I refuse to discuss how today went as it was a day that was mostly a no good very bad day and I would like to go to Australia type day.  But some days are just like that.  Although I am happy that I’ve found out what was causing my pickup to DANGO compiled by Haley Stien   7 | P a g e  ✉hxs12a@acu.edu make a really bad noise and it is NOT a no good very bad thing that is going to cost me lots of money (cost me $6).

We tested the mylar mRPC over the weekend and didn't get the results we had been wanting. So we took it out of the stand and saw that the anti-coating hadn't quite done its job since the sheets of mylar were sticking together. So we changed it to a simple glass rpc and have been testing that this week. We've also been taking apart, cleaning and then remaking two mRPC's made out of very thin glass. Hopefully we'll be able to test those next week. During our spare time we finished editing our CEU abstracts and started working on our posters.   DANGO compiled by Haley Stien   2 | P a g e  ✉hxs12a@acu.edu Au Revoir, Cecily   FROM HALEY STIEN: Diggity Dango,  This week I worked on assembling a glass mRPC with some assistance from Matt. Since this is the first one I’ve done without too much help from Cecily, I was relatively pleased that I only made one tiny mistake that took a mere 3 hours to fix! I’ll count that as a win. I was also happy to submit my abstract on Friday. I just want to be in Canada already dontcha know! Besides that, I know we’ve been taking data on the mRPCs, but that’s more of a Cecily/Aric project. This week I’m hoping to finish building another glass mRPC, get some data on a 3D printed mRPC, and work on my poster a bit.   Less than a week! Haley  FROM ARIC TATE: Hello everyone, This week we focused on getting good data from glass RPCs. It has been a mix of gas leaks, high voltage fluctuations, and low voltage failures. Despite this we remain hopeful that cosmic events will be seen. Our last week looks to be filled with taking more data and removing cables from the PHENIX IR.  -Aric  FROM MATTHEW KIMBALL: *LOL-ing*  FROM DR. TOWELL: Hello Dango, This week has seen us doing a little bit of everything at BNL.  Unfortunately, with just one more week here it feels like our list of tasks to complete is getting longer and not shorter. I don’t know how we will get everything done before we have to go. As we’ve been taking apart the RPC systems of PHENIX, we’ve accumulated a nice pile of equipment that needs to be shipped to ACU and UIUC.  We have decided that we will buy wooden crates to ship the equipment back to ACU and that we will just consolidate the parts for UIUC and store them for later transport to Urbana.  The wooden crates arrived at the lab today, but it’s not clear if the union workers can transport them across the lab before next Tuesday.  Assuming we get the crates, we will load them with the spare RPC1s, FEE, HV, cables, and gas distribution parts. In the TOF lab, we’ve finally really started making progress on several different prototypes.  We’ve got the glass we needed to rebuild the mRPCs with the world’s best timing resolution.  We’ve repaired the pressure vessel to test the mylar mRPCs and we are taking a long set of data this weekend with the world’s first 3-D printed mRPC. Fun stuff. DANGO compiled by Haley Stien   3 | P a g e  ✉hxs12a@acu.edu One thing we thought we’d get to do a good bit of this summer was to disconnect a bunch of PHENIX subsystems.  Today we finally got permission to start doing that for the south RPC1 chambers.  So next week we will be working on that, removing more detectors from the tunnel, packing equipment to ship to ACU, and continue testing mRPCs.  I think we’ve got a full week ahead of us.   Grace and peace, Rusty      FROM VICENTE ROJAS: For the past seven weeks, most of the work I did, if not all, was related to civil environmental engineering. Environmental engineering deals with the purification of water through water and wastewater plants, solid waste treatment, remediation of contaminated sites, among other things. This week, I got a glimpse at what civil transportation engineering looks like. Abilene is looking to fix the streets in the downtown area. There have been multiple complaints about their current status, and the City has retained eHT to work on this project. Two Engineers in Training (EIT) and I inspected 8 blocks this week. We tried to do it as early as possible in order to avoid traffic and heat. I have continued to work on several other projects including the addition and dosing of several new chemicals to water treatment plants in Missouri City and Midland, performance simulations of manufacturer’s reverse osmosis technologies, and report editing.  -Vicente      FROM CALEB HICKS: <Generic Greeting>, This week was fairly productive. I worked the day shift Saturday and Sunday, during which I generated all the Monte Carlo events I need for my project. I took Monday and Thursday off, but spent the rest of the week generating plots and analyzing the data I'd generated. Also on Wednesday I spent a few hours making ribbon cable, though fortunately most of it was finished on Thursday, when I wasn't working. Even with the days I had off, I made fairly good progress this week.  <Generic Send-off>, Caleb Hicks  DANGO compiled by Haley Stien   4 | P a g e  ✉hxs12a@acu.edu FROM ZHAOJIA XI: Bonjour everyone, This week I spent some time working on my abstract and personal contribution.  I am very thankful to those people who gave me comments and feedback. Last week Josh and Dr. D got lots of cables out of the seaquest floor. In order to reuse these cables, another thing we did this week was cutting, testing and labeling these cables.   Can't believe there's only one week left, Zhaojia(Tiffany) Xi  FROM JOSHUA MARTINEZ: Wassup DANGO Amazing news, I finally finished the light tight box! Well almost, I have a few more holes to drill into it. But I have been able to start testing some of the scintillators in a way that I didn't initially plan for but it seems to be working rather well. Hopefully, I get all these holes drilled and some precious precious data by the time we leave. In other news, I get to go on a Muon G-2 tour today that I'm really excited for. My tour guide for the NuMI Underground tour works there and told us a lot about it. I'm praying it lives up to my expectations.  Until Next Time, Joshua Daniel Martinez    FROM PAUL CARSTENS: Salutations! The penultimate week has been filled with panic and cables. Lots and lots of cables... At the start of the week the database that I'd started my magnet study on shut down for a couple days leaving me to restart it on a different database. Then, several days into my second attempt I learned that the runs I was using were incorrectly labeled with the wrong geometry tables. Now, on my third attempt it turns out something is still very wrong as jTracker is now producing significantly fewer dimuons than it was previously.  In less panicky more cable-y news, the ACU students have produced over 100 ribbon cables for the new station 1. We took bundles of old ribbon cables from beneath the floor, cut them to size, attached the leads, and tested their connections. We've still got another 50 cables to go, but these ones will be shorter so they should go faster.   Nearing the end,  Paul Carstens  FROM REUBEN BYRD: Hi Dango, This week I spent a lot of time working on my abstract, and trying to tie up loose ends of things I have done throughout the summer. As a group we also spent a lot of time making ribbon cable. To be more precise, we make 112 21 foot cables are are in the process of making DANGO compiled by Haley Stien   5 | P a g e  ✉hxs12a@acu.edu 56 more 3 foot cables. These will be installed into the detector of the shutdown. As much fun as it was, I think I had my fill of cutting and coiling ribbon cable. I can't believe there is only one more week for us at SeaQuest! I will spend the last week gathering things I will need for my poster and running a last few things through sqerp.  'Til next week, Reuben  FROM DR. MIKE DAUGHERITY: Hi Dango, It’s been a fun week as always.  We stayed in downtown Chicago last weekend while my wife was at the law librarian's conference.  Chicago has world-class museums, the best architecture in America, and amazing food.  This year we finally made it to the Field Museum of Natural History and the Museum of Science and Industry.  Having fun adventures has always been one of my favorite things about summer research. SeaQuest is still chugging along, but the experiment is really telling us that the run has been going on a little too long.  We are playing air conditioner whack-a-mole in our building.  There are three separate A/C units for our building, and when one breaks it makes the others run too long and conk out or freeze up.  It feels like we are paying penance for all the gloating we've done about our cool Chicago summer.  To make things worse, we're helping load and unload giant dewars of liquid nitrogen as we're sweltering in the building.  I've been sorely tempted to "accidentally" dump a few hundred liters of liquid nitrogen in the office. Unfortunately, we need them for the targets since a temporary power outage caused some of the liquid deuterium target to evaporate.  We only need to make it one more week.  Gotta catch em all, -Dr D  FROM DR. ISENHOWER: Dear Dangoites, This is my last entry for July.  I will be gone for the next two weeks (be back onAug. 5).  Cindy and I are taking a long planed, long looked forward to, tour of the Canadian Rockies on a fancy train called the Rocky Mountaineer.  It’s a 2-week trip and we will be enjoying it. This week has been mixed.  I fixed 4 HV 1445 contollers only to have one have a tantallum capacitor blow up and destroy components nearby today.  Another one was destroyed when a tantulum capacitor developed a dead short, started smoking and then exploded.  The weird thing is that now that power supply, after removing that capacitor on the -15V power will put our -15V, but no longer puts out +15 or +5 Volts.  The 1445 Controller boars no longer works that I was using at the time, so I am not happy!  We still have three spares, so I’m content, but in my work to find more DANGO compiled by Haley Stien   6 | P a g e  ✉hxs12a@acu.edu that 2 spare low voltage spares, I’m killing off my other spare controllers.  I think I may stop at the two spares.  The problem is that these things have basic mistakes in their design that I was taught as a freshman not to do, so I have no idea who they let design the circuits or review their work. Hope everybody gets their CEU applications in on time!  Dr. I.

I've been finishing up measurements for the Electronics Study and writing it up. I actually just finished the rough draft so I am excited for a relaxing weekend to come. Other than that there isn't much to report.  Have a good weekend, Matthew Kimball  FROM CECILY TOWELL: LOL Dango, Made it back from Honduras this week, it was a super amazing trip. We made 36 houses, held a clinic for 3 days, DANGO compiled by Haley Stien   2 | P a g e  ✉hxs12a@acu.edu hosted 3 VBS's and did lots more. Unfortunately I was sick a few days after we got back so I only worked on Thursday and Friday. At work we just began making another mRPC for testing, which is always super fun.   Laters, Cecily Towell  FROM ARIC TATE: Hello everyone, Still waiting on r134-a (freon) so that we may resume testing the 6 gap mRPC. A 3 stack, 15 gap mRPC is in the midst of being built while we wait to test the 6 gap mRPC. Besides that, we have done some exploring of the PHENIX remains with the hope of participating in deconstruction sometime in the near future. I have also started to revisit my NIFFTE alpha rate analysis, oh how I missed it.  -Aric  FROM HALEY STIEN: Hey Dango,  This week I helped disassemble and reassemble an mRPC made with non-static Mylar. I also learned that unsteady hands and soldering do not go well together, especially for innocent bystanders (Cecily). Other than that, I spent some time trying to get LaTeX on my computer and fitting some of the graphs from the electronics study with equations. Now I think I need to start figuring out what I’m going to write about for the CEU.. which is kind of stressing me out.  -Haley  FROM DR. TOWELL: Hello DANGO, It is great to be Dango-ing with you again.  During the two weeks that Cecily, Ensley, Travis, and I were away we worked with a group of about 50 Christians on a mission trip to Honduras.  We were blessed to be part of this group that shared God’s love.  We provided food, water, medicine and shelter for many of the poor there.  We returned to the good ol USA just in time for the fourth of July.  That was excellent timing, because I needed an extra day of rest. This week the BNL team has started assembling a 15 gap mRPC, written a PHENIX tech note on the high frequency performance of our electronics, salvaged racks of spare gas parts, and improved a NIFFTE alpha rate study.  In addition to these fun tasks, I’ve had the joy of expense reports, budgets reports, subcontract renewals, transfer agreements, research reports, and other red tape.    The deadline for CEU is coming soon.  Time to start writing up your work.  Also, don’t forget to get a passport if you don’t have one.  Grace and Peace, Rusty DANGO compiled by Haley Stien   3 | P a g e  ✉hxs12a@acu.edu    FROM VICENTE ROJAS: Spending the 4th of July in Abilene was very enjoyable. Monday morning, I went to the Hillcrest parade and had homemade ice cream. For lunch, I met up with ten Korean students who are taking an ACU summer camp at a ranch in Buffalo Gap. I was assigned two new projects this week. The first one had to do with the addition of a chemical feed system to an existing water treatment plant in Missouri City, TX. Given the recent floods in that area, manganese levels increased. The presence of manganese in water can leave stains in tubs and sinks. Manganese is not hazardous and it is considered a secondary drinking water standard. I started off by looking at existing plant drawings and gathering specification sheets for different instruments. I did some drawings of my proposed chemical feed system and presented them to Jordan, my boss.  My second project consisted of receiving a crash course on preliminary desalination design. I was assigned to look at the performance of reverse osmosis (RO) systems from four different manufacturers. RO is a process in which different chemicals are removed from the water as they pass through porous materials. RO is an extremely effective technique given that it removes up to 97% of undesirable chemicals from the water. Each RO manufacturer had their own software simulations that only showed their products. Multiple iterations had to be run with each software in order to find the product that would give the best results. I finally got the software simulations working appropriately on Friday.   -Vicente      FROM CALEB HICKS: <Generic Greeting>, This week started with Monday off for the holiday, and then I had night shift Tuesday. I didn't work Wednesday since I needed to fix my schedule from shift, so I really only started normal work on Thursday. I finally got something to work on though. I am working on making a root macro compile with sqerp. I've made some good progress on tests, so I've actually got a lot done this week considering I've only worked a couple days.   <Generic Send-off>, Caleb Hicks  DANGO compiled by Haley Stien   4 | P a g e  ✉hxs12a@acu.edu FROM ZHAOJIA XI: Hola Dango, This week is awesome! I started taking day shift since Wednesday, everything goes well until today. We had several short chamber HV alarms, so lowered the HV for D2U from 1645v to 1600v. While I am taking shift, I am very close to finish my code. I finally got real data for hodoscope efficiency this morning, so I am twisting my code and let the program read data. This afternoon Paul, Caleb, Josh and I went to a tour which is about D0 and Tevatron. D0 is a detector where proton and anti-proton collisions happened. The tour was amazing, we have learned a lot about particles and high energy physics. Besides taking shift, on Monday and Tuesday I went to Chicago to visit my mom's best friend, she is very close to me so I call her mom. We went to international museum of surgical science, did some shopping and went to see fireworks in downtown on July 4th. Also I got my favorite drink (Caramel green milk bubble tea) in Chinatown. We had a great time and I am so glad that I got to visit this beautiful city again.  Talk to y'all soon, Zhaojia(Tiffany) Xi  FROM JOSHUA MARTINEZ: Wassup DANGO, To start I want to hope everyone had a great Independence Day and are enjoying the short work week. To sum up my week a lot of progress has been made on our project but we still have a long way to go. Tuesday was somewhat unproductive because I needed to use hand power tools (mainly a Jigsaw) but I did not have the "Hand Power Tools Safety Training" done. Most of the day Tuesday consisted of trying to figure out when this training class is offered so I can start working on my project only to find out near the end of the day the class was no longer offered. By the time this was figured out the day was consumed by the collaboration meeting held every Tuesday afternoon. Wednesday I began to cut the add-on for our cosmic ray stand and unfortunately I only had plywood and a Jigsaw. As any carpenter would know, if you are cutting plywood you would like a nice table made out of Sawhorses, a larger sheet of plywood, and a circular saw. With these items you can make cuts that are smooth and that will fit together nicely. Unfortunately I did not have these so my cuts are not the smoothest, and if you ever used a Jigsaw to cut plywood you will believe me when I say this. I had and upper body workout that will last me the rest of this year. Thursday I started to assemble the box and thankfully the sealant we are using to make the box light tight seems to be filling in all the holes and gaps very well. The only problem we have now is the fact that we ran out of sealant, which is the only thing prohibiting us from advancing any further with this project. Friday we plan on taking a tour of D0 and Tevatron DANGO compiled by Haley Stien   5 | P a g e  ✉hxs12a@acu.edu in the afternoon so hopefully we get more sealant before then so we can make a little more progress today.   Sincerely, Joshua Daniel Martinez  FROM PAUL CARSTENS: Greetings! Things have been accomplished! Despite losing a couple days to night shift, I've made good progress on the Cosmic Death Lazer Test Stand (name pending). I got the test hodoscope's voltages all measured and set to appropriate levels earlier this week, and yesterday I started measuring cosmic ray flux. The result was a bit lower than expected, but still well within reason. Since the proper measurements of the SiPM efficiency can't be done till the extension is complete and checked for light leaks, and because taking cosmic ray background measurements is very slow work, I'll be filling in for Reuben by working on some jTracker analyses for the next couple of days.  -Paul  FROM REUBEN BYRD: Hi Dango! So I'm currently (and have been all week) working at a summer camp, so I don't have much to report on. I'm working the owl shift this next week though, so that should be exciting.  Peace, Reuben  FROM DR. MIKE DAUGHERITY: The SeaQuest experiment is semi-officially in the "just keep charging ahead until the end of summer" phase.  We've reached the point where we will ignore any problems we possibly can and just keep taking data until the run ends.  This is always an interesting operations challenge.  Little problems accumulate during the 9-month run period.  You fix what you can (or what you can't live without) and everything else waits until after the run.  For example, the D2U drift chamber started acting up on Friday.  It is at least a four day job to remove it, fix it, reinstall it, survey the new position to a tenth of a millimeter, and start running again.  At this point we are better off running at a lower voltage and reduced efficiency instead of fixing it.  These are the same choices racing teams make in lap 460 of the Indy 500.  In other words, this is a good time to keep an extra roll of duct tape handy. While it is awesome that the run was extended by several weeks and that ACU is here to take so much great data, we are all a little disappointed to miss the shutdown.  It is a lot of fun to run downstairs and finally get to fix everything.  But, as always, we do the best we can with what we've got.  -DrD DANGO compiled by Haley Stien   6 | P a g e  ✉hxs12a@acu.edu In Other News..

I'm proud to introduce Lupe, the hardest working member of the SeaQuest shift crew.” –Dr.D  Group Updates   FROM CECILY TOWELL: Feliz día de rosquilla Dango, This week our fearless leader has returned with backup. We are quite happy that my mother has arrived, as we will not have to depend on our own cooking abilities as much. Haley has done enough damage in the kitchen. On Tuesday we began our 8am-4pm shift, and I am once again the DAQ operator. This go around is a bit different from last time since it’s during the day when all of the experts are here working. People pester us a lot more, and it’s much harder to take a good run of data since they’re always messing with stuff. But it is a nice opportunity to ask these people questions and learn from them; they have a slightly better idea of what’s going on than we do. We are also continuing our work on the paper about Liquid Fluorine Thorium Reactors during our downtime on shift, which is pretty DANGO compiled by Haley Stien   2 | P a g e  ✉hxs12a@acu.edu often right now. I would also like to report that after years of searching, we have discovered some baby groundhogs. Our mission for the coming week is, of course, to capture them.   May you eat many doughuts, Cecily   FROM HALEY STIEN: Hi Dango,  This week we started our day shifts at PHENIX and I think I might actually prefer the owl shift. Having experts and generally concerned people hovering over you adds a lot more pressure. However, there is more opportunity for learning so that’s one benefit. We’re also still working on the paper about Liquid Fluorine Thorium Reactors, so I’ve been researching the Molten-Salt Reactor Program and their Molten-Salt Reactor Experiment that took place in the 1960’s. Pretty interesting stuff! In other news, the Towell clan has arrived. They make us real food sometimes so that I don’t burn my quesadillas every day. There is also a caterpillar apocalypse upon us but I’m staying (relatively) calm as long as they do not infiltrate our apartment.   Hope you all had donuts this week, Haley  FROM MATTHEW KIMBALL: Dear DANGO, This last week has been utterly uneventful, not that I'm complaining. Legitimately nothing of great importance or excitement has happened. After our adventures last week we settled down and worked on some material Dr. Towell left for us over the weekend. Sunday was the closest thing I had to an adventure when the girls asked if I was ready to go to church without letting me know about the lunch or beach plans afterwards. The beach part fell through (not too mad because khakis and a polo are not even remotely beach clothes) but lunch was phenomenal.  To top off an uneventful week, yesterday we experienced an access day and there was no beam for our entire eight hour shift. This has been restful though, so it all evened out.  Sincerely, Matthew Kimball  FROM ARIC TATE: Hello Everyone, I am currently in A-town preparing for the drive to NY. As far as work goes, I am writing a report concerning the work I did while at LANL. Yay \LaTeX!  - Aric  FROM DR. RUSTY TOWELL: Hello DANGO, I hope everyone enjoyed Memorial Day and found a moment to reflect on the blessings we enjoy in this country and the price that has been paid for us to enjoy those blessings.  This week most of my DANGO compiled by Haley Stien   3 | P a g e  ✉hxs12a@acu.edu family and I drove from Abilene to Long Island.  It seems like this trip gets a bit longer each year.  I’m glad I have a couple months before I have to do it again in reverse.  After arriving at BNL on Wednesday, I’ve spent the past two days addressing administrative red-tape and coordinating the work we will begin doing next week and for the rest of the summer.  It looks like we will again work on prototype mRPCs in Mickey’s lab.  Unlike last year, a lot has been done since we were here last summer including a beam test at FNAL. We hope to build mRPCs made of glass, mylar, and 3D printed material.  After building them we will use the cosmic stand we built last year to test them.  Grace and Peace, Rusty    FROM VICENTE ROJAS: If you got into engineering hoping that there would never be any more writing, editing, or revising to do, you are WRONG.  I am glad to be reporting back to DANGO after a two-year absence. This summer I was hired by Enprotec / Hibbs & Todd (eHT), a local civil engineering firm from Abilene, TX. Something interesting about my hiring process was that I never had a formal interview. I met two professional engineers (PE) from eHT, who are now my bosses, through the events that ACU’s Engineering and Physics Department hosted in the Spring semester. I introduced myself to them and asked questions, lots of engaging questions.  As a student, if you meet a possible employer and get their contact information, follow up with an email. Show them that you are interested. Also, always have a resume ready with you. My first day at eHT started out by meeting Daniel, the other intern who I share an office with, and filing paperwork in order to get paid. Afterwards, I got a small project assigned by Jordan Hibbs, PE, who is one of my bosses. He had me work with another engineer. She and I looked at site plans from a water treatment plant at Midland, TX and reported back to Mr. Hibbs. In the afternoon, I met with Josh Berryhill, PE, and had a four-hour long meeting where he brought me up to speed with the different projects that he is working on. There were a ton of acronyms and terminology that I did not know, but I tried to stay with him. It was intense.  I have spent the last three days reading the material that Mr. Berryhill gave me. We are talking about 50+ page reports that engineers at eHT have written. I will soon be writing and revising those reports myself. I feel like I am DANGO compiled by Haley Stien   4 | P a g e  ✉hxs12a@acu.edu studying for a test, but I do not know when the test will be. The Fluid Mechanics, Special Topics Civil Engineering, and Engineering Economics courses that I took in previous semesters are paying off.  When I first accepted this position, I was told that my assignments will vary from day to day. I wish this week was more exciting, but I understand that I first need to study and become familiar with eHT’s projects.    I did not anticipate that this would be a four-day work week. After coming back from Torreon, Mexico, Monday‘s break allowed me get settled back into my house. Aside from my job, I have tried to stay well rested and dry. It has been a rainy week in Abilene.  -Vicente    FROM ZHAOJIA XI: Hello researchers, This is Tiffany again. At the beginning of this week, I continued working on sqerp. This program is used to compute track momentum using KMAG bend plane deflection and track through FMAG and computer dimuon closest approach. I changed KMAGPTKick value +/- 5% made a plot to show the relationship between different KMAGPTKick values and their charges and momentum. On Thursday Dr.Chen asked me to look into a program which was written by Dr. Chuck Brown. The code is used to check Drell-Yan dimuon pairs, calculate efficiency for hodoscope and other things that I am trying to understand. Also the program was written in Fortran which is a programming language that I have never seen before. I am doing my best to learn and use it, hopefully  I will be able to improve this program.  Talk to yall soon, Zhaojia(Tiffany) Xi  FROM CALEB HICKS: <generic salutation>: Another week without much to report. I don't have the nice owl shift hours anymore so I have to be awake during the day. I feel like I could sleep for about 28 hours straight. We're supposed to get projects to work on, but so far we haven't heard anything. I've just been taking the time to brush up on c++. We've also been learning a lot about nuclear physics, so that's good too.   <generic send-off>, Caleb Hicks  FROM JOSHUA MARTINEZ: Wassup DANGO,      This week as of now was rather uneventful. Memorial Day was nice to have off and a good start to the week. Tuesday was just a regular day and DANGO compiled by Haley Stien   5 | P a g e  ✉hxs12a@acu.edu besides the weekly meeting nothing interesting happened. Wednesday we had a talk about Dark-Photons which was rather fun. We also went to a talk about the SSC (Super Colliding Super Conductor) and who was responsible for its downfall. Thursday we had a really great lecture from Dr. D about Linux and my virtual machine that I learned a lot from. Currently (Friday) I am giving myself a crash course in C++ coding language and will continue to do so over the weekend. I believe around 1:00 pm today I will be helping SeaQuest replace/upgrade a high voltage power supply in the beam tunnel, I am looking forward to that. As much as I love sitting at my laptop pressing keys and making code it will be great to finally get out of this chair and do some hands on work. Until next time DANGO.  Sincerely, Joshua Daniel Martinez  FROM PAUL CARSTENS: Not dead yet! With Memorial day off and Friday not done yet, it's been a short week thus far and there isn't much to report. We've had our usual lectures from Dr.s I and D on physics, electronics, and computer science with the most notable being an explanation of the weak force that wasn't just "this is the force you don't explain to your non physics friends". The only task I've had this week was repairing two more HV serial cables with Reuben's assistance. In other news, it looks like we'll all have projects soon! Most likely two of us will be assigned to work on the dark photon experiment and the rest will be repairing the jTracker program.  FROM REUBEN BYRD: Hey Dango, This week we got a little more insight into what we will be working on over the summer. Paul and I will be working with sqerp and trying to get that back up and running. This is the event tracker, but the creator left, so it hasn't been in use. Hopefully we'll get it working! On Friday we also replaced on of the high voltage crates, we had to where hard hats and everything, it was the whole shubang.   'Til next week,  Reuben  FROM DR. MIKE DAUGHERITY: Hi DANGO, We will always try to make a plan and guess what we'll be doing at the labs, but we never really know.  We find out what things need to be done and what things we think we can do, and hope that there's an overlap.  This week revealed that we'll be spending our summer tracking things through SeaQuest.  In addition to picking up the responsibilities of running SQERP for the collaboration, we're also getting started on something a little more exotic. DANGO compiled by Haley Stien   6 | P a g e  ✉hxs12a@acu.edu SeaQuest is designed to track muons.  The proton beam splats into the target and the five meter block of iron behind it producing several kajillion particles, many of which can decay into muons.  Every now and then we see a pair of muons coming from the target and by measuring these we learn about anti-quarks in the proton.  But suppose the muons can from somewhere else.  One theory (which is crazy or brilliant, or perhaps both) is that dark matter could produce muon pairs well behind the target.  If we can figure out how to look for these, then we can say something about whether or not "dark photons" exist. So, it wasn't part of the original plan, but ACU is now in the dark matter business.      -Dr. D  FROM DR. DONALD ISENHOWER: Dear Dangoland from Dr. I. at Fermilab. My time has been continued to be spent repairing LeCroy 1440 High Voltage systems.  On Thursday morning I reached my goal of having two complete systems, plus two extra controllers so that a system could go back in to put us back in normal operating mode.  Once I announced that, it was decided to get them in ASAP, which is non-trivial because it has to taken down to the pit with the crane and only two people have the training to use it.  One is on vacation and the other was sick, but we got it arranged for Friday at 1 p.m. (the one who was sick agreed to come up to do it).  So Caleb helped me for an hour or two Thursday putting in the HV modules exactly as they would be used for the H2 hodoscope plane, putting in the HV values, and measuring all the actual values to make certain that every channel worked correctly.  Of course a problem cropped up, but I had that solved by 9 p.m.. Friday morning, knowing these supplies are unreliable, I prepared a second crate exactly like the previous one and verified all channels.  The students got to help crane it in Friday afternoon.  We hooked it up to the network and …..  it didn’t work.  So I went back got a spare controller and then got it up and running.  So just the bouncing of moving it downstairs was enough to cause that module to fail, reinforcing my warning of the need for spares. Caleb helped move the cables from the temporary system back to the reinstalled system and everything came back up.  Some hodoscope channels that we thought we were having problems with turned out to be due to the temporary system, so I was the hero of the moment.  I stayed until 8 p.m. to be available to go back in and fix any problem that cropped up.  I’ve fixed 3 controller modules in the last couple of weeks, where Fermilab has not been able to repair any in the last 9-12 months.  I’m working on repairing other modules, but they’re different as they are the ones with sections that are lethal if you touch the wrong place.  :-) DANGO compiled by Haley Stien   7 | P a g e  ✉hxs12a@acu.edu People have suggested as there are now no sites that can repair these power supplies and that there are still lots of experiments still using them that I could start a business repairing them.  My response is that they would have to be willing to pay very dearly to get me to do this for anybody else!  -Dr. I. the elder  Picture of the week candidates  Matthew: “Mobbed by tickling birds.”     Zhaojia: “Geeeeeeeese”   Dr. D: “Paul in a funny hat!”       DANGO compiled by Haley Stien   8 | P a g e  ✉hxs12a@acu.edu Coffee of the Week   SagTown Coffee- Caramel Macchiato

I thought I'd submit a DANGO that sums up what I've done so far before I go back to Abilene. I've spent my time working for Dr. Willis (and the LIGO Scientific Collaboration) at the Max Planck Institute for Gravitational Physics (AKA the Albert Einstein Institute) in Hannover, Germany since the second week of May. I started out by learning lots and lots of Python so I could carry out the tasks that I needed to get done. The collaboration analyzes data in a few different methods. One such method utilizes PyCBC, which is Python software that analyzes the coalescence of binary black holes. I started out by testing DANGO compiled by Haley Stien   2 | P a g e  ✉hxs12a@acu.edu whether we can see the same results from a data run when running on a GPU instead of a CPU. While this might be an easy task for many, it took me a while since I was learning Python along the way. In late May, I attended a conference about the future of gravitational wave research. Stephen Hawking was supposed to be in attendance, but he got sick near the start of the conference. :( Oh well. It was still an enjoyable and informative conference. Next, I worked on changing various parameters to increase the efficiency of data analysis runs. That is still on going, and will probably continue back in Abilene (as far as I know). Now I know what you're thinking: is this all I've done while in Germany? That's so lame! And you'd be right (mostly, although I did go with Josh and Autumn to some lovely places early on). That's why I've tried to make up for all the weekends I stayed in Hannover by travelling this week! I started out in Berlin for some aggressive sightseeing. I went to the Museum Island, which was phenomenal, but really shouldn't be done in the time period I did it. I saw the Berlin Wall, Brandenburger Tor, Under den Linden, and various other things. The next day I went to Potsdam to Sanssouci Palace, and then to Charlottenburg Palace. Next was Leipzig! A beautiful town with lots of history. I think my favorite part was seeing the church J.S. Bach used to work at. The next day I went back to Hannover and slept all day. Next was Hamburg. I was surprised to see a harbor there, which is apparently quite famous. I blame America that my only association with the city involves fast food. It was extremely hot that day, so I mostly stayed indoors. I'd say my favorite part was looking out over the city from a church tower. On Friday I went to Nuremberg to learn some history. And Saturday I went to Munich. I could go on forever about these trips, so I've kept it as short as I possibly can. All in all, it was an amazing and fulfilling experience, and I cannot begin to describe the impact it had on me.   Auf wiedersehen! Hannah    FROM MATTHEW KIMBALL: Hey DANGO Matthew here, This week has been a good one here at Brookhaven. We finished out our lasts shifts at PHENIX (which will be shutting down after the current shift is done) and moved back to Mickey's lab. We immediately picked back up where we left off our electronics work and tested the  bandwidth of two different balun boards and two different drs4s. The next step will be to measure the drs4s when their input DANGO compiled by Haley Stien   3 | P a g e  ✉hxs12a@acu.edu is put through the balun boards.  See ya, Matthew Kimball  FROM ARIC TATE: Hello Everyone, This week was a doozy. Unfortunately the mRPC decided to stop producing signals sometime over the weekend. We assumed that the pre-amplifiers were blown and took the mRPC of the of gas vessel to check them. They weren't. So after reattaching everything we placed the mRPC back in the vessel and began flowing gas. We are now waiting on Mickey (who is on shift for most of the day) to be around before we turn on the electronics. He would like to see the initial signals we observed last Friday and make sure we don't blow any more oscilloscope channels. At this point we have no good leads on why the mRPC stopped working.  Also, Muhlenberg has begun invading our fortress and I do not know how much longer we can hold out. We will offer up Haley first if it comes to that.  -Aric  FROM HALEY STIEN: Hey Dangoers,  This week has gone by somewhat quickly. I began my week finishing up my last shift and I actually had to train someone who hadn't already done the job, which helped make my last day go by a bit faster. On Wednesday, Matt and I finally went back to working in the lab on our electronics study. For the most part, it's pretty repetitive, but I did learn how to solder wires (sort of)! That was my excitement for the week. Also, because most of the Towells are gone, I've had to really step up my cooking game. I made pasta! However, I am really looking forward to my mom's visit in a few days so that I can go eat a bunch of awesome food in NYC.  Contrary to popular opinion, I do not mind the Muhlenberg invasion and have embraced our new friends (not literally).  Ready for vacation, Haley    FROM VICENTE ROJAS: I spent most of this week figuring out a puzzle. Have you ever sat down and tried to put together a 10,000 piece puzzle? It requires A LOT of concentration and dedication. Maybe I exaggerated with the number of pieces, but this is how this week felt. I was assigned to find the gravity and pump hydraulic calculations of an entire water treatment plant in Brady, TX. This means that I had to make a model that DANGO compiled by Haley Stien   4 | P a g e  ✉hxs12a@acu.edu showed the flow of water with a given pressure, elevation, and flow rate through thousands of feet of piping. I sat down for endless hours, looking at old plans and deciphering the appropriate piping connections. I kept myself motivated knowing that once I had this under my belt, anything else would be a piece of cake.  I discovered that one of the perks of working at eHT was getting lunch paid for from Beehive Restaurant to attend a webinar. The webinar discussed the recent changes in the process to become a Professional Engineer. I am still a long ways from becoming a PE, but it is good to know about these changes.  Lastly, I started my online speech class this past Monday.   -Vicente    FROM ZHAOJIA XI: Ni hao Dango, This week has been productive and fun. My mentor Andrew has come back from vacation, so I got to ask him many questions about the project and made a lot of progress. From Monday to Wednesday, I was working on my code. The program is to read hodoscope efficiency from different tracks in various counters. On Thursday, Dr. Daugherity's family, Reuben and I went to six flags. The weather was perfect, most lines were not too long. I had a blast with these cool people. I am covering half of Catherine's day shift right now and I will keep working on my code and ask Andrew what else he wants me to improve. I hope nothing will crash during the shift and finish writing code very soon.  Work hard play hard, Zhaojia(Tiffany) Xi  FROM CALEB HICKS: <Generic Greeting>, This week I'm back from shift and have been trying to keep myself busy poking through some code and reading things. I helped Dr. I build a cosmic ray detector from some hotoscopes so we can eventually test some new scintillators. I've been trying to talk to Dr. D about dark photon stuff because I was kind of lost but he's been absent so I haven't gotten much done on that other than poking through code. Kind of boring week, but I got a little done.   <Generic Send-Off>, Caleb Hicks  FROM JOSHUA MARTINEZ: Dear DANGO, This week was rather interesting in that I was working night shift this week so I had a lot of time to do things. I manage to read an entire book over C++ and Linux so I feel like my programming skills have improved significantly compared to the DANGO compiled by Haley Stien   5 | P a g e  ✉hxs12a@acu.edu beginning of this internship. I have also been working on looking at data from some of the databases and I have become comfortable searching through all the information. In terms of being on shift I have learned how to correct the Chamber high voltage for all the drift chambers. It seemed rather hard at first but after I tried it myself it wasn't so difficult. Other than that it was a rather smooth week.   Sincerely, Joshua Daniel Martinez  FROM PAUL CARSTENS: Greetings, all, I've spent this week on shift so nothing too noteworthy has happened in my work. The detector was nice and cooperative while I was watching it; I didn't have to panic and scramble while everything around me crashed and burnt. While on shift I continued to work on the magnet PT kick study that I had started last week. I significantly reduced the mass difference between the Monte-Carlo J/psi and the jTracked J/psi. It's not perfect and I'm sure I could reduce it further given more time, but it's time I move on to optimizing the PT kick settings for the MC drellyan events. It'll likely be less clean than the J/Psi since the mass isn't a well-defined point. Once I get the MC drellyan cooperating I'll move onto real data.    FROM REUBEN BYRD: Greetings Dango, This week I have been stumbling my way through a macro to graph the residuals of each detector. It's putting my limited programming experience to the test, which good I guess! In other news, we set up a cosmic test stand at the beginning of the week, but we haven't done much with it since Dr. I left. I'm assuming we will work more with that this coming week. On Thursday I went with the Daugherity family and Tiffany to Six Flags! We had a blast, and no one even threw up! I'll be working the four to midnight shift this weekend, and I'm hoping for smooth sailing with the beam.  Adieu, Reuben  FROM DR. MIKE DAUGHERITY: DANGO!  I recently realized that I've already been here for six weeks. Time flies when you're smashing atoms.  We are still chugging along with SQERP and making great progress in writing a tool that will import data from the dark photon simulation into a SeaQuest tracker.  And sooo many shifts this week.  Also Six Flags.  All in all, a good week.  -DrD   DANGO compiled by Haley Stien   6 | P a g e  ✉hxs12a@acu.edu FROM DR. DONALD ISENHOWER: News from Dr. I. the elder: I have set up a muon test trigger and needed electronics for the extruded scintillators for the dark photon search experiment.  Also I spent time teaching Ruben and Caleb how it works so that they will be able to finish setting it up and start testing them with the SiPms that we will use for readout.  Right now there are three of those silicon photomultipliers down in the SeaQuest detector to see how they survive the radiation environment.  Lots of electronics doesn’t survive more than a few months even if it is behind the shielding of the solid magnet.  Any silicon device in the target cave would be dead after one beam pulse, which is why the idea of putting a monitoring camera in the area isn’t possible. We will have to add a patch panel to a light-tight box built by Ben Draper, a former ACU student some of you may have met at our Awards banquet because we have a number of new signals we have to get in and out of the box.  We of course have to keep the box light-tight and many connectors will let a few photons through and our detectors will pick up single photons.  The students will also participate in solving the problem in how to mount the new hodoscopes.  Depending on where they are mounted, this can be an easy or hard problem.  But attaching the SiPMs to the fibers will still be tricky.  Dr. I.
