Thin Scintillation Counters in Particle Detectors

Abstract

The paper deals with the design and parameters of thin scintillation counters, not more than several mm thick, with a large geometric aperture. Such counters with high light yield and, accordingly, with high detection efficiency of charged particles are widely used in nuclear and particle physics, as well as in facilities for beta contamination monitoring of clothing and various objects by extracting signals of low-energy electrons against a background of gamma radiation. In these applications just the minimum thickness of the scintillator with the required large geometric dimensions of the detector determines the high efficiency of the counters.
