Abstract :
The results of light yield (LY) measurements of 2×2×8 mm3 and 2×2×10 mm3 LuYAP and LYSO pixels are compared with Monte-Carlo simulations of equivalent systems performed with the light ray tracing program LITRANI. It is shown that the differences in LY observed for different setup configurations are well explained by the different light collection efficiencies ηL of the setups derived from the simulations. Combining the results on LY and ηL for a reference system makes it possible to determine the absolute light yield LYabs for LuYAP and LYSO.
