Improved physical and mathematical model of a semiconductor gamma radiation detector based on the use of the statistical tests method

Relevance of research. The relevance of the study is due to the fact that neutron activation analysis (NAA) is one of the convenient ways to determine the composition of samples of natural and man-made origin. Among such objects are unique samples of rocks, minerals, condensates, dust, "hot" particles, etc. In this case, the effectiveness of the analysis depends on the applied methods and techniques. NAA is highly sensitive (up to 10-14 g), multi-element, non-destructive, less dependent on the mass and composition of the sample, on the forms of finding the elements. The main aim: the main purpose of the study was to obtain an HPG model of the detector using Monte Carlo simulation of the interaction of gamma-rays with the detector crystal. Research objects: the detector response was obtained experimentally and with the help of a neutron-physical model. Research Methods. The main tool used for instrumental neutron activation analysis is a semiconductor detector based on highly pure germanium crystals under the general label HPGe (HPG)...
