ICARUS: perspective for sterile neutrino search at FermiLab

ICARUS T600 liquid argon TPC completed in 2013 a very successful three years run at LNGS underground laboratory exposed to CNGS neutrino and cosmic rays. The relevant physics and technical results achieved proved the full maturity of the LAr-TPC technique and the impact on the neutrino and astroparticle physics. The T600 will be exposed to Booster neutrinos in the framework of the joint ICARUS, SBND and MicroBooNE effort to definitely clarify the sterile neutrino puzzle.
