Summary

The ICARUS T600 Module is the largest liquid argon detector (760 t LAr mass) ever realized to study neutrino oscillations and matter stability in the deep underground Gran Sasso Laboratory. One of the key elements for the detector performance is the liquid argon purity: residual electronegative compounds in argon have to be kept as low as 0.1 parts per billion all over the detector run. The T600 Module design was finalized by the ICARUS Collaboration after years of R&D studies that brought to the viable and scalable industrial solutions necessary for sized experiments with severe safety prescriptions for the underground operation. We present the T600 Module successful commissioning and the 3-years efficient, stable and continuous operation with extraordinary LAr purity, high performance and zero dead time data taking. This result demonstrates for the first time the feasibility of activation and long-term run in safe conditions of sized cryogenic detectors even in a confined underground location and represents a milestone for future neutrino projects at higher mass scale (MODULAr, ICARUS-NESSIE, LBNE, LBNO…).
