The results of a study of some ways to improve spectroscopy characteristics of the CdZnTe quasi-hemispherical detectors when working in high gamma radiation fluxes are presented. It was shown that the use of IR illumination with a wavelength of 1050 nm or 1200 nm or at slight warm-up of the detector to +30°C … +40°C can significantly improve spectroscopy performance of the CdZnTe detectors of size 3.5 mm × 3.5 mm × 1.75 mm when operating in a tested gamma-radiation field with a dose rate up to 590 mGy/h.
Key words: CdZnTe (CZT) / gamma-radiation detectors / semiconductor radiation detectors / room temperature semiconductor detectors / infra-red (IR) illumination / IR LED / high flux gamma-radiation / leakage current / voltage-current characteristic
