Abstract

A fast, unique method for determining phosphor scintillation spectra by means of an electronic apparatus is described. A major advantage is that all of the controls are digital. This includes coincidence timing to determine whether an x-ray absorption event has occurred as well as control of the time window during which the number of light photons emitted in response to an x-ray absorption event is counted, and storage of the photon count itself. The apparatus and its logic are described in detail. The scintillation spectra and the resulting calculated Swank coefficient values of several phosphors obtained with this apparatus are presented as examples.
