Исследование эффективности регистрации гамма-квантов полупроводниковым германиевым детектором

Abstract

The object of the study is the efficiency of detecting gamma rays with a semiconductor detector Canberra GC1518. The purpose of the work is to determine the change in the efficiency of gamma-ray registration by a coaxial germanium Canberra GC1518 detector in time and to develop a methodology for assessing changes in registration efficiency associated with an increase in the thickness of the dead layer of a semiconductor crystal. As a result of the study, a change in the efficiency of detecting gamma rays by a semiconductor detector in the period from 2016 to 2020 was established, a methodology for assessing the effectiveness of detecting gamma rays by a detector was developed.
