The ICARUS-T600 liquid argon (LAr) time projection chamber (TPC) detector is currently deployed as a far detector of the Short Baseline Neutrino (SBN) program at Fermilab (USA) to search for a possible LSND-like sterile neutrino signal at Δm2≈1 eV2 with the Booster (BNB) and Main Injector (NuMI) Neutrino Beams [1]. A global physical event rate of ≈0.6Hz, including the genuine neutrino interactions in LAr, beam halos and cosmic interactions inside the proton pulse time windows, is expected, roughly corresponding to ≈4 PB of data for the total 6.6×1020 protons on target exposure if the full ICARUS-T600 detector is read-out (≈200 MB event size). The designed trigger system described here would collect the genuine neutrino interactions with a ≈95% expected efficiency.
