Abstract
Optical properties of large size lead fluoride (PbF2) crystals of three different manufacturers and their degradation caused by 60Co γ-radiation have been investigated. Transmission losses have been systematically studied at absorbed energy doses between 0.1 and 7 kGy. Several radiation induced absorption bands have been observed. Optical bleaching with light of wavelengths ≳365 nm has been found very effective to restore the original characteristics even after repeated irradiations. This observation together with the high density and the ultraviolet extended transmission make PbF2 an excellent choice for high rate and high resolution e.m. calorimetry.
