ICARUS

A 760-ton liquid argon time projection chamber mapping neutrino interactions at Fermilab with millimeter precision.

The ICARUS detector (Imaging Cosmic And Rare Underground Signals) operates as the far detector for the Short-Baseline Neutrino program at Fermilab. It employs 760 tons of ultra-pure liquid argon to visualize neutrino interactions in three dimensions. Originally pioneered at CERN by Nobel laureate Carlo Rubbia, the hardware moved to Illinois in 2017 to investigate the sterile neutrino: a theoretical particle that could reshape our understanding of physics. By capturing ionization electrons and scintillation light, ICARUS delivers the high-resolution imaging required to solve long-standing anomalies in the Standard Model.
