Description
The ICARUS collaboration employed the 760-ton T600 detector in a successful three-year physics run at the underground Gran Sasso National Laboratory (LNGS), performing a sensitive search for LSND-like anomalous $\nu_e$ appearance in the CERN Neutrino to Gran Sasso beam. This contributed to the constraints on the allowed neutrino oscillation parameters to a narrow region around 1 $eV^2$. After a significant overhaul at CERN, in July 2017, the T600 detector was shipped and installed at Fermilab. In 2020, the cryogenic commissioning began with detector cooling, liquid argon filling and recirculation. ICARUS then started its operation, collecting the first neutrino events from the Booster Neutrino Beam (BNB) and the Neutrinos at the Main Injector (NuMI) beam off-axis, which were used to test the ICARUS event selection, reconstruction and analysis algorithms. ICARUS successfully completed its commissioning phase in June 2022, moving then to data taking for neutrino oscillation physics, aiming at first to either confirm or refute the claim by Neutrino-4 short-baseline reactor experiment. In addition, ICARUS will perform measurement of neutrino cross sections in liquid Argon with the NuMI beam and conduct several Beyond Standard Model (BSM) searches. After the first year of operations, ICARUS will search for evidence of sterile neutrinos jointly with the Short-Baseline Near Detector (SBND), within the Short-Baseline Neutrino (SBN) program. In this presentation, preliminary results from the ICARUS data with the BNB and NuMI beams are presented both in terms of performance of all the ICARUS subsystems and their capability to select and reconstruct neutrino events.
