The comparison of scintillation properties of YAP:Ce, YAG:Ce and ZnO:Ga powders as a potential substitution of LSC cocktail

The work investigates the possibility of substitution of a traditional liquid scintillation cocktail by a scintillation powder with grain size up to 30 mu m. Based on previous research, YAP:Ce, YAG:Ce and ZnO:Ga powders were selected. The parameters, which often affect the measurement, were tested, such as pH and OH-, geometry, efficiency and activity linearity dependency, the amount of scintillator as well as secondary parameters such as afterglow, temperature dependency and repeatable usage. All parameters were simultaneously tested and compared with an AquaLight scintillation cocktail.
