Features of radiation damage of BGO crystals grown by the low-thermal-gradient Czochralski technique
Abstract
We examined the effect of the radiation damage on optical and scintillation properties of BGO crystals produced by the low-thermal-gradient Czochralski growth technique. Irradiation tests were performed for γ-ray doses from 1 krad to 10 Mrad. Optical absorption and light output were measured upon irradiation and self-recovery. Based on the shape of radiation-induced absorption, degradation of transparency and light output upon radiation damage as well as their self-recovery, two distinct types of BGO crystals were established.
