Abstract

This paper addresses the use of Visible Light Photon Counters (VLPCs) for detection of light induced in light arrays of small scintillating crystals for gamma ray imaging. The use of plastic step-index-of-refraction fibers for collecting the scintillation light for detection by a VLPC is examined and data obtained in initial exploratory experiments are discussed. The results are compared with the number of detectable scintillation photons predicted by a model that in essence treats the crystal as an integrating cavity with highly efficient diffuse reflecting surfaces.
