Description
The Short-Baseline Neutrino (SBN) project at Fermilab (USA) uses three Liquid-Argon Time Projection chambers (LArTPCs) located along the Booster Neutrino Beamline (BNB) to search for anomalies in muon neutrino disappearance and electron neutrino appearance at short baseline. The ICARUS T600 detector, with its active volume of 760t of liquid Argon, will act as a far detector for the experiment. The detector is also located off-axis to the NuMI beamline, which offers the opportunity for ν-Argon cross-section measurements in an energy range of interest for the next generation long-baseline experiment DUNE. The photodetection system of ICARUS deploys 360 Hamamatsu R5912-MOD PMTs, covering one-third of the total internal surface of the detector, and has a major role in the experiment trigger, identification of neutrino signals, and rejection of cosmic background. This poster will describe the design, optimization, and preliminary performance of the ICARUS trigger system using more than 100·1018 POT from the BNB and 180·1018 from NuMI collected since June 2021.
