Test and characterization of 20 pre-series hamamatsu R5916-MOD photomultiplier tubes for the ICARUS T600 detector

Abstract

ICARUS T600 will become the far detector of the Short Baseline Neutrino program at FNAL (USA), which foresees three liquid argon time projection chambers along the Booster Neutrino Beam line. The apparatus is now under refurbishing at CERN. A new light detection system is foreseen, using four planes of photo-multiplier tubes (PMTs) with 90 units each. A first pre-series of 20 PMTs Hamamatsu R5912-MOD, 8 in. diameter suitable for cryogenic applications, was fully tested, both at room and at liquid argon temperature, to ensure good performance of the detector.
