摘要

This paper reports proton induced radiation damage in fast crystal scintillators. A 20 cm long LYSO crystal, a 15 cm long CeF3 crystal and four liquid scintillator based sealed quartz capillaries were irradiated by 800 MeV protons at Los Alamos up to 3.3 x 10(14) p/cm(2). Four 1.5 mm thick LYSO plates were irradiated by 24 GeV protons at CERN up to 6.9 x 10(15) p/cm(2). The results show an excellent radiation hardness of LYSO crystals against charged hadrons.
