A precise model of a 40% relative efficiency p-type HPGe detector was created for photon detection efficiency calculation using the MCNP code. All detector parameters were determined by different experiments. No experimental calibration points were used for the modification of detector parameters. The model was validated by comparing calculated and experimental full energy peak efficiencies in the 40-2754 keV energy range, for point-source geometry with the source-to-detector distance of 25 cm.
利用MCNP代码创建了一个相对效率为40%的p型高纯锗探测器的精确模型，用于计算光子探测效率。所有探测器参数均通过不同实验确定。未使用实验校准点来修改探测器参数。通过比较在40 - 2754 keV能量范围内点源几何结构（源到探测器距离为25 cm）下计算得到的和实验测量的全能峰效率，对该模型进行了验证。
