The results of light yield (LY) measurements of 2×2×8 mm 3 and 2×2×10 mm 3 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 η L of the setups derived from the simulations. Combining the results on LY and η L for a reference system makes it possible to determine the absolute light yield LY abs for LuYAP and LYSO.
