Design, construction and tests of the ICARUS T600 detector

The authors have constructed and operated the ICARUS T600 liq. Ar (LAr) time projection chamber (TPC). The ICARUS T600 detector is the largest LAr TPC ever built, with a size of ∼500 tons of fully imaging mass. The design and assembly of the detector relied on industrial support and represents the applications of concepts matured in lab. tests to the kton scale. The ICARUS T600 was commissioned for a tech. run that lasted ∼3 mo. During this period all the detector features were extensively tested with an exposure to cosmic-rays at surface with a resulting data collection of ∼30,000 events
