20.500.12556/RUL-153067 Slow control of the Belle II Aerogel Ring Imaging detector Since 2018, an Proximity Focusing Aerogel Ring Imaging Detector (ARICH) efficiently separates hadrons in the forward end-cap of the Belle II spectrometer. Cherenkov photons emitted in the double-layer aerogel radiator are expanded in 16-cm space and detected on the photon detector, which consists of 420 hybrid avalanche photodiodes and rear readout electronics operating in threshold mode. Each of the sensors requires six different high voltages and a supply of four low voltages for the electronics. Because of the power dissipation, the system also includes a cooling system in which cold water circulates through the Al tubes thermally connected to the readout electronics. Reliable control of supply voltages and monitoring of environmental data and sensor status ensure stable operation of the ARICH detector and early response to sudden changes in current, single event disturbances, overheating, and other faults. In this paper, we introduce the ARICH’s slow control system and the data quality monitor used to track performance. proximity focusing RICH with an aerogel radiator operation slow control true false true Angleški jezik Ni določen Članek v reviji 2023-12-15 15:43:15 2023-12-15 15:43:16 2023-12-16 03:49:06 0000-00-00 00:00:00 2023 0 0 5 str. art. 168569 Vol. 1056 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 539.1 0168-9002 10.1016/j.nima.2023.168569 169713155 1-s2.0-S0168900223005594-main.pdf 1-s2.0-S0168900223005594-main.pdf 1 5BEE7516ABE3BC1959BD7403BED2A97F 3db1999dda59487e82ee9e4d4bb6839a2c4593a75a82d19deac2c2de532d7d1d b95f0b76-9b58-11ee-bebf-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=178871 https://www.sciencedirect.com/science/article/pii/S0168900223005594 0 702f6ad2-9b58-11ee-bebf-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=178870 Fakulteta za matematiko in fiziko 0 0 0
