Abstract

This work investigates in some details the conditions and parameters affecting and controlling the performance of three different types of HpGe spectrometers. The quality and accuracy of any results depend on the optimum working parameters. The major geometrical and electronics parameters were comprehensively studied and validated for n- and p-type germanium detectors. The spectrometers, at the optimized conditions, were then used for analysis of IAEA reference materials as quality control measure. The Angel-3 software was also used with standard point sources for generation of efficiency curves. The results of the optimized parameters verification for enhancing the systems performance, the minimum detectable activity (MDA), the figure of merit (FOM) and specific activity (SA) assessment were precisely validated, calculated and discussed with equations, figures and tables presentations.

优化参数的验证，以提高伽马能谱仪的性能和功效

摘要

这项工作详细研究了影响和控制三种不同类型的HpGe光谱仪性能的条件和参数。任何结果的质量和准确性都取决于最佳的工作参数。对主要的几何和电子参数进行了全面的研究，并针对n型和p型锗探测器进行了验证。然后，在最佳条件下使用光谱仪对IAEA参考物质进行分析，作为质量控制手段。Angel-3软件还与标准点源一起使用，以生成效率曲线。精确验证了用于增强系统性能，最小可检测活性（MDA），品质因数（FOM）和比活（SA）评估的优化参数验证结果，
