The ICARUS experiment

Abstract

The 760 ton liquid argon ICARUS T600 detector performed a successful threeyear physics run at the underground LNGS laboratories, studying neutrino oscillations with the CNGS neutrino beam and searching for atmospheric neutrino interactions in cosmic rays. A sensitive search for LSND like anomalous ve appearance has been performed, contributing to constrain the allowed parameters to a narrow region around Δm2 ~ eV2, where all the experimental results can be coherently accommodated at 90% C.L.. After a significant overhauling, the T600 detector will be exposed at Fermilab to the Booster Neutrino Beam acting as the far detector, in order to search for sterile neutrino within the SBN program. In the present contribution, the ICARUS LNGS achievements, the present status of the detector and the ongoing analyses also finalized to the next physics run at Fermilab will be addressed.
