Abstract

The signals from high-Z scintillating crystals such as PbWO4 and BGO contain a significant Cherenkov component. We investigate methods to determine the contribution of Cherenkov light to the signals generated by high-energy electrons and pions (mips), both statistically and event-by-event. These methods are based on differences in the spectra, the time structure and/or the directionality of the two types of light. The electron signals, and their composition, are also analyzed as a function of the age (or depth) of the shower.
