This paper reports proton-induced radiation damage in fast crystal scintillators. Large size LYSO and CeF_3 crystals of 20 and 15 cm long were irradiated by 800 MeV protons at Los Alamos up to 3.3 × 10^(14) p/cm^2 with degradation and recovery of their longitudinal transmittance measured in situ. LYSO plates of 14×14×1.5 mm^3 were irradiated by 67 MeV protons at UC Davis up to 9.5 × 10^(13) p/cm^2, and 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.

This work has benefited from the use of proton beams in the LANSCE facility at LANL, the CROCKER facility at UC Davis and the IRRAD facility at CERN. The authors would like to thank Drs. R. Hirosky and M. Mulhearn, who helped us to irradiate the LYSO plates at UC Davis, and F. Ravotti and D. Bailleux, who helped us to irradiate the LYSO plates at CERN. Many useful discussions with Drs. G. Dissertori, F. Nessi-Tedaldi and C. Woody are acknowledged.
