Luminescence and Scintillation Characteristics of Gd₂SiO₅: Ce Single Crystal Scintillator

Abstract:

The luminescence and gamma-ray detection properties of Gd₂SiO₅: Ce single crystal scintillator were investigated. The light yield (LY) and energy resolution were measured using R6231 photomultiplier. At 662 keV γ-rays, high LY of 10,300 photons /MeV and good energy resolution of 6.4 % were obtained. The intrinsic LY and light loss coefficient under excitation with 662 keV γ-rays were evaluated. The mass attenuation coefficient for 662 keV γ-rays was also measured by transmission method and compared with the theoretical value calculated by WinXCom program.
