摘　　要：为确定高能电子在加速器重金属靶物质中的射程，用蒙特卡罗方法计算能量为1～100MeV的高能电子在加速器常用的重金属靶物质（金、钨、钽、钼）中的射程。将1～20MeV电子在钨靶中射程的计算结果与已发表数据进行对比，计算结果与已发表数据符合较好。对射程计算结果进行数值拟合，得到了实用性较强的1～100MeV宽能区内电子在常用加速器靶物质中的射程计算公式。该公式可为高能电子加速器靶的设计计算提供参考数据。In order to determine the range of high-energy electron moving in accelerator target, the range of electron with the energy range of 1 to 100 MeV moving in common target material of accelerator was calculated by Monte-Carlo method. Comparison between the calculated result and the published data were performed. The results of Monte-Carlo calculation are in good agreement with the published data. Empirical formulas were obtained for the range of high-energy electron with the energy range of 1 to 100 MeV in common target material by curve fitting, offering a series of referenced data for the design of targets in electron accelerator.
