Abstract
Because of their superb energy resolution and detection efficiency scintillation crystals are widely used in high energy and nuclear physics experiments. A crucial issue is radiation damage in crystals. We report an investigation on γ-ray induced radiation damage in various crystal scintillators of large size, including BaF_2, BGO, CeF_3, pure CsI, LSO/LYSO/LFS and PWO, with an integrated dose up to 340 Mrad and a dose rate up to 1 Mrad/h. Optical and scintillation properties of these crystal samples were measured before and after irradiations. The results show that pure CsI has good radiation hardness below 100 krad. BaF_2, BGO and LYSO have good radiation hardness beyond 1 Mrad. In terms of light output degradation LYSO is clearly the best among all scintillation crystals.
