摘要: Radiation damage effects in lutetium, yttrium and gadolinium oxy-orthosilicates, Lu2SiO5:Ce, Y2SiO5:Ce, Gd2SiO5:Ce under γ- protons irradiation have been investigated. Crystals were irradiated with a 60Co gamma source to total dose of 2000 Gy high-rate 24-GeV proton beam at CERN PS, fluence ~3.6 ×1013 p/cm2. Color centers created irradiation, phosphorescence its mechanism the crystals are discussed.
