Abstract :
We have obtained optically clear samples of LuAP:Ce from the Institute of Physical Research, Ashtarak, Armenia, measuring up to 5×5×40 mm3. The photo electron yield for a number of these samples was measured with a Philips XP2020Q photomultiplier tube, and 556 photo electrons per MeV was obtained for the best samples. This is comparable to what is obtained from BGO crystals under the same condition, but a factor of 5 less than what is obtained with an LSO sample of similar dimensions. The light in LuAP:Ce increases with cerium concentration between 0.13 and 0.47%
