R&D results on a CsI-TTGEM based photodetector

The very high momentum particle identification detector proposed for the ALICE upgrade is a focusing RICH using a C4F10 gaseous radiator. For the detection of Cherenkov photons, one of the options currently under investigation is to use a CsI coated Triple-Thick-GEM (CsI-TTGEM) with metallic or resistive electrodes. We will present results from the laboratory studies as well as preliminary results of beam tests of a RICH detector prototype consisting of a CaF2 radiator coupled to a 10x10 cm2 CsI-TTGEM equipped with a pad readout and GASSIPLEX-based front-end electronics. With such a prototype the detection of Cherenkov photons simultaneously with minimum ionizing particles has been achieved for the first time in a stable operation mode

Qualification Tests of the R11410-21 Photomultiplier Tubes for the XENON1T Detector

The Hamamatsu R11410-21 photomultiplier tube is the photodetector of choice for the XENON1T dual-phase time projection chamber. The device has been optimized for a very low intrinsic radioactivity, a high quantum efficiency and a high sensitivity to single photon detection. A total of 248 tubes are currently operated in XENON1T, selected out of 321 tested units. In this article the procedures implemented to evaluate the large number of tubes prior to their installation in XENON1T are described. The parameter distributions for all tested tubes are shown, with an emphasis on those selected for XENON1T, of which the impact on the detector performance is discussed. All photomultipliers have been tested in a nitrogen atmosphere at cryogenic temperatures, with a subset of the tubes being tested in gaseous and liquid xenon, simulating their operating conditions in the dark matter detector. The performance and evaluation of the tubes in the different environments is reported and the criteria for rejection of PMTs are outlined and quantified.Comment: 24 pages, 16 figure

Kajian Struktur Komunitas Fitoplankton Di Perairan Pantai Desa Tapak Kecamatan Tugu Kota Semarang

Fitoplankton merupakan biota tumbuhan yang bersifat autotrophic dan merupakan produsen primer di perairan. Perairan Pantai Desa Tapak dikelilingi oleh Perumahan penduduk, kawasan industri, dan aktivitas nelayan yang akan menyumbang pencemaran organik maupun pencemaran anorganik. Perairan ini mengalami peningkatan ketinggian permukaan sebagai akibat pasang tinggi rob, yang mengakibatkan penggenangan daerah pertambakan dan sebagian dari estuaria. Penggenangan tersebut berakibat kepada peningkatan percampuran unsur hara yang diduga akan mempengaruhi keberadaan dan struktur komunitas fitoplankton pada daerah tersebut. Penelitian ini bertujuan untuk mengetahui struktur komunitas fitoplankton yang meliputi kelimpahan, keanekaragaman, keseragaman, dan dominasi fitoplankton di Perairan Pantai Desa Tapak, Kecamatan Tugu, Semarang. Penelitian ini dilaksanakan pada Oktober - November 2013. Metode yang digunakan dalam penelitian ini adalah deskriptif eksploratif, pengumpulan data dengan Sample Survey Method. Sampel fitoplankton diambil secara horizontal dengan planktonnet 37 µm. Sejumlah 3 stasiun pengambilan sampel telah ditetapkan dengan metode pertimbangan (purposive sampling method). Hasil penelitian menunjukkan bahwa struktur komunitas fitoplankton di Perairan Pantai Desa Tapak tersusun atas 3 kelas fitoplankton yang terdiri dari 24 genus fitoplankton, yaitu kelas Bacillariophyceae (17 genus), kelas Dinophyceae (5 genus), dan Cyanophyceae (2 genus). Genus yang mempunyai kelimpahan tertinggi adalah Skeletonema, Thalassionema, Thalassiothrix, dan Pleurosigma dari kelas Bacillariophyceae. Kelimpahan fitoplankton rata-rata berkisar 25.426 – 34.100 sel/m3. Nilai keanekaragaman berkisar 1,68 – 2,05, dimana tertinggi pada stasiun II dan terendah pada stasiun III. Keseragaman berkisar 0,66 – 0,76, dimana tertinggi pada stasiun II yang diikuti dengan stasiun I dan stasiun III.

Perkembangan Hukum Islam Di Indonesia Pada Masa Kerajaan Islam Sampai Dengan Masa Reformasi

Hukum Islam adalah aturan-aturan Ilahi yang diamanahkan kepada Nabi Muhammad saw untuk disampaikan kepada umat manusia terkhusus kepada umatnya baik aturan hukum yang berupa akidah (kepercayaan) maupun aturan hukum yang berkaitan dengan suatu amaliyah (perbuatan). Hukum Islam merupakan aturan Allah yang memiliki sifat statis (tetap bersumber pada al-Qur’an dan Hadits dalam segi kehidupan) dan sekaligus dinamis (mampu menjawab segala permasalahan sesuai dengan perkembangan zaman, situasi dan kondisi, serta dapat ditempatkan dalam segala macam bentuk struktur sosial kehidupan, baik secara individu maupun secara kolektif bermasyarakat)

Resonant Third-Integer Extraction from the PS2

For the proposed PS2 accelerator several extraction systems are needed, including a slow third-integer resonant extraction. The requirements are presented together with the conceptual considerations for the sextupole locations and strengths, the separatrices at the extraction elements and the aperture implications for the overall machine. Calculations of the phase space separatrices have been computed with a new code for the physics of slow resonant extraction, which is briefly reviewed. Implications for the extraction equipment design and for the injection-extraction straight section optics are discussed

Turnaround time for early infant HIV diagnosis in rural Zambia: A chart review

Background: Early infant HIV diagnosis is challenging in sub-Saharan Africa, particularly in rural areas where laboratory capacity is limited. Specimens must be transported to central laboratories for testing, leading to delays in diagnosis and initiation of antiretroviral therapy. This study was undertaken in rural Zambia to measure the turnaround time for confirmation of HIV infection and identify delays in diagnosis. Methods: Chart reviews were conducted from 2010-2012 for children undergoing early infant HIV diagnosis at Macha Hospital in Zambia. Relevant dates, receipt of drugs by mother and child for the prevention of mother-to-child transmission (PMTCT), and test results were abstracted. Results: 403 infants provided 476 samples for early infant diagnosis. The median age at the "6-week" and "6-month" assessments was 8.1 weeks and 7.0 months, respectively. The majority of mothers (80%) and infants (67%) received PMTCT. The median time between sample collection and arrival at the central laboratory in Lusaka was 17 days (IQR: 10, 28); arrival at the central laboratory to testing was 6 days (IQR: 5, 11); testing to return of results to the clinic was 29 days (IQR: 17, 36); arrival of results at the clinic to return of results to the caregiver was 45 days (IQR: 24, 79). The total median time from sample collection to return of results to the caregiver was 92 days (IQR: 84, 145). The proportion of HIV PCR positive samples was 12%. The total median turnaround time was shorter for HIV PCR positive as compared to negative or invalid samples (85 vs. 92 days; p = 0.08). Conclusions: Delays in processing and communicating test results were identified, particularly in returning results from the central laboratory to the clinic and from the clinic to the caregiver. A more efficient process is needed so that caregivers can be provided test results more rapidly, potentially resulting in earlier treatment initiation and better outcomes for HIV-infected infants
