The gamma–ray Detection Device is based on a HPGe detector with Electric Machine Cooling which is intended for the conversion of Gamma-ray quantum energy using amplitude electric signals and their amplification for further registration with a nuclear physics apparatus. It was specifically developed for long, continuous operations.
