Radiation Damage of Oxy-Orthosilicate Scintillation Crystals Under Gamma and High Energy Proton Irradiation

Radiation damage effects in lutetium, yttrium and gadolinium oxy-orthosilicates, Lu_2SiO_5:Ce, Y_2SiO_5:Ce, Gd_2SiO_5: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 P...

Descripción
Sumario:Radiation damage effects in lutetium, yttrium and gadolinium oxy-orthosilicates, Lu_2SiO_5:Ce, Y_2SiO_5:Ce, Gd_2SiO_5: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 ×10^13 p/cm^2. Color centers created under irradiation, phosphorescence and its mechanism in the crystals are discussed.
