Abstract

We report on recent tests and computer simulations of a sub-millimeter pitch CdZnTe strip detector under study as a prototype imaging spectrometer. This paper presents new measurements and new analyses of previous measurements of the CdZnTe transport properties for this prototype and resolves previously reported quantitative discrepancies. Measurements of charge signals produced by α-particles are used to determine the transport properties. These are then used in the model to predict detection efficiencies and spectroscopic performance for γ-rays that are compared with the data
