Proton induced radiation damage in fast crystal scintillators

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 3.3×10^(14)p/cm^2. Four 1.5 mm thick LYSO plates were irradiated by 24 GeV protons at CERN up to 6.9×10^(15)p/cm^2. The results show an excellent radiation hardness of LYSO crystals against charged hadrons
