Abstract

The General Unwanted Energy Rejection Analysis Program (GUERAP-3) computer program is designed to predict instrument stray light performance. In this paper, we discuss an atypical application of the program as an illustration of a much wider variety of problems for which the program is useful. The application discussed here is light collection modeling in scintillation detectors. The optical attenuation of light scintillations produced by gamma rays and charged particles can be modeled, and the light collected by a photomultiplier tube (PMT) can be optimized as a function of geometry of the scintillator, its surface characteristics (polished, rough ground, reflective foil-covered, etc.), PMT placement, and volume absorption within the scintillator. Necessary modifications to the standard GUERAP-3 computer program are discussed. The modified program is used to predict the optical attenuation of a typical scintillation detector. These predicted results are shown to agree with experimental data, thus demonstrating the use of GUERAP-3 for such analyses.
