Radiation damage in BaF2 crystals
- 1. Brookhaven National Lab., Upton, NY (United States)
Description
This paper reports on the effects of radiation damage and recovery that have been studied in BaF2 crystals exposed to 60Co radiation. The change in optical transmission and scintillation light output have been measured as a function of dose up to 4.7 x 106 rad. Although some crystals exhibit a small change in transmission, a greater change in scintillation light output is observed. Several 25 cm long crystals which have been irradiated show large changes in both transmission and light output. Recovery form radiation damage has been studied as a function of time and exposure to UV light. A long lived radiation induced phosphorescence has been observed in all irradiated samples which is distinct from the standard fast and slow scintillation emissions
