The performance of a CdZnTe detector for measuring charged particles from the reaction d (He-3,alpha)p has been evaluated at proton and alpha particle energies of approximately 13 and 2MeV, respectively. The energy resolution observed from this in-beam study highlights the potential of these detectors for use as ancillary detectors for channel selection in nuclear spectroscopy.
