ResumoGAGG(Ce) is a novel scintillator with a fast response and high light output without a hygroscopic nature. It is expected to be a useful detector for charged particles at high-counting rates. However, the response of the GAGG(Ce) scintillator to charged particles has not been fully examined. In the present work, the light output and energy resolution of the GAGG(Ce) scintillator were measured for protons and alpha particles at Ep=5–68 MeV andEα=8–54 MeV as well as gamma rays atEγ=662 keV from a 137Cs source. The results were compared with those of the CsI(Tl) scintillator. The scintillation efficiencies dL/dE of the GAGG(Ce) and CsI(Tl) scintillators were obtained and parametrized as a function of linear energy transfer dE/dx.
