Paper Abstract

Analytical considerations and test results bearing on the performance of a CsI(Tl) scintillating crystal coupled with a photodiode when used as a gamma-ray spectrometer are addressed. Laboratory test results on a number of CsI(Tl) bars with different sizes, diffusive coatings, and preamplifier designs are presented. A suitable event selection electronic logic design is shown which reduces the effect of noise on the count rate while retaining the desired energy threshold.
