ICARUS at the Fermilab Short-Baseline Neutrino Program -- Initial Operation
ICARUS Collaboration

TL;DR
ICARUS at Fermilab has successfully begun operations after upgrades, collecting initial neutrino data to investigate neutrino oscillations, sterile neutrinos, and other fundamental physics questions in the Short-Baseline Neutrino program.
Contribution
First operational data from the upgraded ICARUS detector at Fermilab, enabling new searches for sterile neutrinos and other phenomena in the Short-Baseline Neutrino program.
Findings
Collected initial neutrino events from BNB and NuMI beams.
Tested event selection, reconstruction, and analysis algorithms.
Laid groundwork for sterile neutrino and BSM searches.
Abstract
The ICARUS collaboration employed the 760-ton T600 detector in a successful three-year physics run at the underground LNGS laboratory studying neutrino oscillations with the CERN Neutrino to Gran Sasso beam (CNGS) and searching for atmospheric neutrino interactions. ICARUS performed a sensitive search for LSND-like anomalous appearance in the CNGS beam, which contributed to the constraints on the allowed parameters to a narrow region around 1 eV, where all the experimental results can be coherently accommodated at 90% C.L.. After a significant overhaul at CERN, the T600 detector has been installed at Fermilab. In 2020, cryogenic commissioning began with detector cool down, liquid argon filling and recirculation. ICARUS has started operations and successfully completed its commissioning phase, collecting the first neutrino events from the Booster Neutrino Beam (BNB) and the…
