The detection efficiency of a broad-energy germanium detector was determined empirically and compared to predictions by the Monte-Carlo software GEANT4 and FLUKA . The considered source geometries were point-like, filter paper and a water beaker. Calculations were performed in the photon energy range of 30–1836 keV . Simulated detection efficiencies obtained from both Monte-Carlo software were found to be in a good agreement (typically <5%) with experimental results for the considered source geometries. A comparison between the detection efficiencies obtained with GEANT4 and FLUKA codes exhibited a good agreement with a robust average of approximately 1%.

宽能锗探测器的全能峰效率的蒙特卡洛模拟-GEANT4和FLUKA的比较

经验确定了宽能锗探测器的探测效率，并将其与蒙特卡洛软件GEANT4和FLUKA的预测结果进行了比较。所考虑的源几何形状为点状，滤纸和水烧杯。计算是在30-1836 keV的光子能量范围内进行的。从两种Monte-Carlo软件获得的模拟检测效率与考虑的源几何形状的实验结果非常吻合（通常<5％）。用GEANT4和FLUKA编码获得的检测效率之间的比较显示出很好的一致性，其稳健平均值约为1％。
