The ICARUS (Imaging Cosmic And Rare Underground Signals) collaboration is investigating signs of physics that may point to a new kind of neutrino called the sterile neutrino.
Other experiments have made measurements that suggest a departure from the standard three-neutrino model. ICARUS is also investigating the various probabilities of a neutrino interacting with different types of matter as well as neutrino-related astrophysics topics.
The project originated in Italy before it spent two years undergoing upgrades at CERN. It moved to Fermilab in 2017 and was installed in its detector hall in 2018, where along with the new Cosmic Ray Tagger, it forms the far detector for the Short-Baseline Neutrino program.
