Abstract :
A simple MC simulation using the Mathematica app. is presented for a square-shaped PEM device consisted of the notched scintillating crystal chips. For a previously studied material of a 30 mm length Pr:LuAG with the cross sectional area of either 2×2 mm2 or 4×4 mm2, the imaging spread and the detection efficiency of a point source are examined. Chosen the number of DOI notches as a parameter, an optimum solution to give the sub-millimeter space resolution is obtained. Some more results for the PEM construction also are presented.
