Quenching Behavior of Scintillation Light Yield in Ce-doped Gd2SiO5 under Proton and Alpha-Particle Irradiation

Year: 2026

Type: article

Abstract: The scintillation light yield quenching of Ce-doped Gd 2 SiO 5 (GSO) single crystals under proton and 241 Am α-particle irradiation has been investigated.Pulse height spectra of protons with the deposited energies of 1.5-3.4MeV were measured at The Wakasa Wan Energy Research Center.In addition, pulse height spectra of 241 Am α-particles with the deposited energies of 1.62-5.41MeV were measured.By comparing the experimental results of scintillation outputs with simulations, the Birks parameter of GSO was estimated to be 0.01 mm/keV.
