| Popis: | 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. |
