Status and perspective of ICARUS-T600 detector at the Fermilab Short-Baseline Neutrino program

The ICARUS collaboration has employed the 760-ton T600 detector in a successful three-year physics run at the underground LNGS laboratory, performing a search for anomalous ν e appearance in the CERN Neutrino to Gran Sasso beam, which contributed to the constraints on the allowed neutrino oscillation parameters to a narrow region around 1 eV. After a significant overhaul at CERN, the T600 detector has been installed at Fermilab. In 2020 the cryogenic commissioning began with detector cool down, liquid argon filling and recirculation. ICARUS started its operation collecting the first neutrino events from the Booster Neutrino Beam and the Neutrinos at the Main Injector 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. In the short term, ICARUS will be able to either confirm or refute the claim by Neutrino-4 short-baseline reactor. At the completion of the Short-Baseline Near Detector, near and far detectors will join within the Fermilab Short-Baseline program searching for evidence of sterile neutrinos. measurements of neutrino cross sections with the NuMI beam and several Beyond-Standard-Model searches. In this presentation, the technical achievements of the ICARUS detector subsystems (Time Projection Chambers, Light Photo-detection System, Cosmic Ray Tagger, Trigger and Data Acquisition) during the commissioning phase and early data taking will be presented; the prospects for the first physics analysis will be reported.
