Abstract

The origin of the fast scintillation component of Ce-doped LiCaAlF 6 crystal excited by gamma ray irradiation was studied with X-ray and vacuum ultraviolet (VUV) irradiation. A fast luminescence component was observed under VUV irradiation and was ascribed to luminescence at defects in the host matrix on the basis of VUV spectroscopy. No fast scintillation component was observed in the scintillation time profile under X-ray irradiation. The fast scintillation component under gamma ray irradiation can be concluded to be the result of Cherenkov radiation from energetic secondary electrons.
