摘要

给出了用MCNP和EFFTRAN两种不同的编码计算HPGe探测器的总探测效率（TDF）。与实验测量值的比较表明，这两种编码对点源产生了非常相似的结果，但对圆盘状源产生了非常不同的结果。用这些代码计算的TDF来确定真符合和（TCS）的校正，得到了类似的结果。这意味着这种校正不高度依赖于TDF，并且可以使用EFFTRAN来缩短计算时间。

A Comparison of Methods for Determining the Total Efficiency of HPGe Detectors

The total detection efficiency (TDF) of HPGe detectors, calculated using two different codes, MCNP and EFFTRAN, are presented. A comparison with experimentally measured values shows that the two codes produce quite similar results for point sources but very different for disc-shaped ones. Using the TDF calculated with these codes to determine the correction for true coincidence summing (TCS), similar results are obtained. This means that this correction is not highly dependent on the TDF, and it is possible to use EFFTRAN to shorten the calculation time.
