    Efficiency simulation and coincidence-summing correction for HPGe detector by ZHANG Ruiqin, LI Qi, FAN Yuanqing, ZHAO Yungang, ZHANG Xinjun, JIA Huaimao, NIU Yazhou, LI Ruiying, WANG Shilian

    Published 2024-11-01
    “…BackgroundIn order to enhance the detection sensitivity of HPGe detectors for measuring the low-level activity of radionuclides, samples are usually measured as close to the detector as possible to improve the detection efficiency, which inevitably leads to serious coincidence-summing effects in return and affects the accuracy of measured activity.PurposeThis study aims to conduct efficiency simulation and coincidence-summing correction for HPGe detectors.MethodsFirst of all, the peak efficiency of the HPGe detector was simulated by Geant4 and the internal geometry of the HPGe detector was optimized by comparing the simulated results with the experimental results of the mixed standard calibration source. …”
