Liquid Argon Time Projection Chambers in the studies of rare events (phenomena) in particle physics and astrophysics

W ciagu kilku ostatnich dekad, neutrinowa społecznosc naukowa, wykazała olbrzymie zainteresowanie wykorzystaniem techniki ciekłoargonowej i ciekłoargonowymi komorami projekcji czasu (LAr-TPC) do badania rzadkich zdarzen (np. oddziaływanie neutrin czy WIMPów). Działanie ciekłoargonowych komór projekcji czasu polega na pomiarze sladów naładowanych czastek oddziałujacych w ciekłym argonie, pomiarze strat energii w wyniku jonizacji osrodka (dE/dx) oraz identyfikacji oddziałujacych i powstałych czastek. W pracy tej przedstawiona została technika ciekłoargonowa, zalety i wady róznych koncepcji detektora ciekłoargonowego, ich konstrukcja i zasada działania, przykłady mozliwych zastosowan i wyniki jakie mozna osiagnac stosujac ciekłoargonowa komore projekcji czasu. To ostatnie pokazane jest na przykładzie najwiekszego zbudowanego do tej pory ciekłoargonowego detektora projekcji czasu: ICARUSa T600 (760 t LAr, 476 t czynnej masy). Detektor ICARUS T600 z powodzeniem pracował w podziemnym laboratorium w Gran Sasso we Włoszech (LNGS - Laboratori Nazionali del Gran Sasso [1]) od 2010 do 2013 roku. Podczas jego eksploatacji zebrano dane bedace wynikiem oddziaływania, w ciekłym argonie, neutrin wyprodukowanych w osrodku CERN i przesłanych do Gran Sasso (wiazka CNGS [2]). Przeprowadzono takze badania oddziaływan neutrin atmosferycznych. Doskonała rozdzielczosc kalorymetryczna i rekonstrukcyjna detektora pozwoliła na szeroki program badawczy, od rozpadu nukleonu do badania oscylacji neutrin z wiazki CNGS. Wsród badan przeprowadzonych z wykorzystaniem wiazki neutrin mozemy wyróznic trzy główne: (1) weryfikacja zjawiska nadswietlnosci neutrin sugerowanej przez eksperyment OPERA [4], (2) dokładne badanie znikania neutrin mionowych oraz (3) anomalne pojawianie sie neutrin elektronowych. Celem tego ostatniego była eksperymentalna weryfikacja lub wykluczenie nieprawidłowosci w liczbie obserwowanych neutrin elektronowych, sugerowany przez eksperyment LSND [3]. W pracy zostały takze opisane rózne aspekty zwiazane z praca detektora ICARUS T600, poczawszy od zastosowania ciekłego argonu jako medium w którym oddziałuja czastki, przez osiagniecia z zakresu fizyki, do przyszłosci detektora w osrodku Fermilab National Accelerator Laboratory (FNAL [5]) i jego udział w programie badawczym z krótka baza (SBN [6])

Zaremba, G. Zarnecki, M. Ziembicki, M. Zito, S. ZsoldosWe report measurements by the T2K experiment of the parameters θ23 and Δm2 32, which govern the disappearance of muon neutrinos and antineutrinos in the three-flavor PMNS neutrino oscillation model at T2K’s neutrino energy and propagation distance. Utilizing the ability of the experiment to run with either a mainly neutrino or a mainly antineutrino beam, muon-like events from each beam mode are used to measure these parameters separately for neutrino and antineutrino oscillations. Data taken from 1.49 × 1021 protons on target (POT) in neutrino mode and 1.64 × 1021 POT in antineutrino mode are used. The best-fit values obtained by T2K were sin2ðθ23 Þ ¼ 0.51 þ0.06 −0.07 ð0.43 þ0.21 −0.05 Þ and Δm2 32 ¼ 2.47 þ0.08 −0.09 ð2.50 þ0.18 −0.13 Þ × 10−3 eV2=c4 for neutrinos (antineutrinos). No significant differences between the values of the parameters describing the disappearance of muon neutrinos and antineutrinos were observed. An analysis using an effective two-flavor neutrino oscillation model where the sine of the mixing angle is allowed to take nonphysical values larger than 1 is also performed to check the consistency of our data with the three-flavor model. Our data were found to be consistent with a physical value for the mixing angle

Zimmerman,7 M. Zito,53 S. Zsoldos,30 and A. Zykova26 (T2K Collaboration)This paper reports the first simultaneous measurement of the double differential muon neutrino chargedcurrent cross section on oxygen and carbon without pions in the final state as a function of the outgoing muon kinematics, made at the ND280 off-axis near detector of the T2K experiment. The ratio of the oxygen and carbon cross sections is also provided to help validate various models’ ability to extrapolate between carbon and oxygen nuclear targets, as is required in T2K oscillation analyses. The data are taken using a neutrino beam with an energy spectrum peaked at 0.6 GeV. The extracted measurement is compared with the prediction from different Monte Carlo neutrino-nucleus interaction event generators, showing particular model separation for very forward-going muons. Overall, of the models tested, the result is best described using local Fermi gas descriptions of the nuclear ground state with RPA suppression

Global characteristics of (197)Au+ (197)Au collisions at 23 AMeV

Light fragments production and isospin dependences in Sn+Ni and Sn+Al central collisions at 25MeV/A and 35MeV/A from reverse/isospin experiments

This paper presents the physical analysis results for the following reactions: 124Sn+64Ni, 124Sn+27Al, 124Sn+58Ni at 35MeV/A and 25MeV/A. The main goal of this studies was to find observables sensitive to isospin effects and to present the similarities/differences between the systems characterised by various charge asymmetry factor, defined as I = (NZ)=A. Theoretical simulations based on the Quantum Molecular Dynamics (QMD) model have been performed in order to compare them with the results of the analysis of experimental data. The first phase of the reaction was carried out with the code CHIMERA [1]. The sequential decay of hot fragments was simulated by the code COOLER [2]. The conclusions are as follows: there are observables sensitive to the isospin of the system, such as the Light Charged Particles (LCP) emission and their sensitivity is demonstrated more prominently in the analysis of central collisions at 35MeV/A. The theoretical calculations do not reproduce these relations well

Emission of intermediate mass fragments in the p(1.9GeV)+natNi reaction

The emission of the intermediate mass fragments (IMFs; 2 $\le$ Z $\le$ 14) produced in the interaction of 1 .9 GeV protons with nickel ($^{nat}$Ni) has been a subject of interest of the present study. Energy spectra of isotopically and elementally identified ejectiles have been measured at angles 15° and 120° with the respect to the beam direction. The identification of the emitted IMFs has been performed by means of the Bragg curve spectroscopy and the time-of-flight technique (TOF). The Bragg curve detectors (BCDs) were employed for the charge identification, whereas the TOF method combined with the BCD, for the mass identification. The main task of the present PhD thesis was to built appropriate data acquisition system, to perform the experiment on the internal beam of the COSY accelerator, to propose the methodology of the off-line analysis of the data, to apply it to the event-by-event stored data, and to perform the phenomenological analysis of the obtained data. The results, experimental procedures, and different techniques of the element and isotope identification by means of the BCD + TOF are presented. The determination of the power law parameter $\tau$ characterizing the mass and charge distributions of the reaction products is discussed. Various methods of the nuclear matter temperature determination, the comparison between nuclear matter thermometers, and the discussion of the obtained results, shown in the energy-temperature diagram (the so called caloric curve), are presented as well. The results suggest two different mechanisms of the IMFs production : from the equilibrated (IMFs measured at 120°), and non-equilibrated (IMFs measured at 15°) state of the nucleus
