摘要：

The influence of geometrical and optical parameters on the light collection within scintillator assemblies has been investigated. Monte-Carlo calculations predicted a strong dependence on the design of the light guide and the effective reflectivity of its covering. Excellent agreement of experimental and theoretical data is shown for a small “standard”-scintillator (5.08 cm × 5.08 cm in diameter) as well as for large-area systems (5.08 cm × 25.4 cm in diameter). In both cases partially coated light guides should be used to restrict the local dependence of the light transmission to less than 2 % or 4 % resp. over the total volume. The averaged absolute transmission is calculated to be approximately 80 % or 45 % resp. for these optimized setups. Copyright © 1978 by The Institute of Electrical and Electronics Engineers, Inc.
