Possibilities of Using CdZnTe and CeBr3 Crystals for Measuring Photon Radiation in a Wide Energy Range

New semiconductor detectors based on CdZnTe and CeBr3 crystals are tested. A spectrometer facility consisting of CdZnTe, CeBr3, and Si (for alpha-gamma measurements) detectors is assembled for verification tests. The main parameters of the detectors such as energy resolution FWHM/E-gamma [keV] and detection efficiency (%) are investigated and measured. The possibilities of measuring photon radiation in a wide energy range are verified. gamma-gamma and alpha-gamma coincidences are measured using the detectors. The results of the measurements show that the detectors can be used to study nuclear reactions and properties of reaction products.
