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 2 SiO 5 :Ce, Y 2 SiO 5 :Ce, Gd 2 SiO 5 :Ce under γ- and protons irradiation have been investigated.

Zusammenfassung: | Radiation damage effects in lutetium, yttrium and gadolinium oxy-orthosilicates, Lu 2 SiO 5 :Ce, Y 2 SiO 5 :Ce, Gd 2 SiO 5 :Ce under γ- and protons irradiation have been investigated. Crystals were irradiated with a 60 Co 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. |
