The present status of the LuAlO{sub 3}:Ce (LuAP) scintillator is reviewed and its performance compared to that of YAlO{sub 3}:Ce (YAP). The light output of LuAP, at this stage of development, appears to be limited by two factors: insufficient Ce concentration and the presence of a parasitic absorption. Both LuAP and YAP show a dependence of light output on thickness, indicating that YAP also suffers from parasitic absorption. Measurements on undoped material offer a clue to the identity of the parasite.
