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 μm. 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.

The author of the article would like to express his gratitude to the company Crytur Ltd. for the lending of YAP:Ce scintillation powder. Also I would like to thank Vaclav Cuba and Jan Barta from CTU in Prague for lending YAG:Ce powder and for some technical advices.
