Abstract

Data have been simulated at 100 and 200 keV for a material representing a generic plastic scintillator and another representing a typical glass scintillator. A plot of the 90% beam broadening diameter of the two materials as a function of scintillator thickness is presented. A corresponding plot of the energy deposition efficiency showed that at any given thickness, the efficiency is about four times higher in the glass than in the plastic scintillator. It is inferred that in all cases and for the same amount of beam broadening, the denser, higher atomic number material gives the best efficiency of energy deposition. Also, using a larger pixel size gives both higher energy deposition and allows for the use of thicker layers of the material.
