Abstract
Radiation damage effects in lutetium, yttrium and gadolinium oxy-orthosilicates, Lu2SiO5 : Ce, Y2SiO 5 : Ce, Gd2SiO5 : Ce under γ and protons irradiation have been investigated. Crystals were irradiated with a 60Co gamma source to a total dose of 2000 Gy and a high-rate 24-GeV proton beam at CERN PS, to a fluence of ~ 3.6 ×103 p/cm 2 Color centers created under irradiation, phosphorescence and its mechanism in the crystals are discussed.
