Abstract

Operation characteristics of CsI(Tl) and CsI(Na) scintillation detectors, to a large degree connected with light collection in crystals, are calculated for various shapes, sizes and reflecting surface types. Allowance is made for the true light reflection indicatrix which is characterized by the effective mirror constituent of the reflected light, p. Its value ⟨p⟩, averaged over incidence angle, is used for the classification of reflecting surfaces. Operation characteristics (in particular, spectrometric ones) are found to be essentially dependent on ⟨p⟩ Tables of operation characteristics, given below, permit one to make inferential conclusions on an optimal combination of the shape, sizes and the reflecting surface version
