Development of CRT muon veto for ICARUS experiment

AbstraktAbstract

The ICARUS (Imaging Cosmic And Rare Underground Signals) program concerns the usage of Liquid Argon (LAr) detector for studies of neutrinos. From LNGS underground laboratory it was moved to CERN to undergo several upgrades and then it was shipped to Fermilab. Together with SBND and MicroBooNE detectors it forms the Short Baseline Neutrino program. The detector will be operating at shallow depth and therefore it will be exposed to the full flux of cosmic rays. Direct way to suppress this problematic background is to surround it with muon veto system tagging incident cosmic muons with high efficiency. This cosmic ray tagger (CRT) is based on large area of scintillating detectors and wavelength shifting fibers. R&D of the CRT basic elements was done at the IEAP CTU in Prague on CERN request. Performed activities resulted in a contract with NUVIA a.s. to deliver 1000 pieces of scintillating detectors. Further, the IEAP team completed a quality check of 120 chosen pieces.
