介绍基于BEPC LINAC和BFEL LINAC(北京正负电子对撞机和北京自由电子激光装置电子直线加速器)慢正电子束设备中正电子源部分的Monte-Carlo模拟过程。结果表明，从Ta靶出射的快正电子产额在BEPC LINAC和 BFEL LINAC运行于兼容模式时分别为1.84×1010/s和3.9×1011/s。若慢化体慢化效率在10-4量级，基于BEPC LINAC和 BFEL LINAC慢正电子束的慢正电子产额分别为106—107/s和107—108/s。

A Monte-Carlo simulation about the positron source used on the BEPC and BFEL LINAC-based slow positron beam lines was reviewed. The results showed that when the BEPC LINAC was operated under parasitic condition, the fast positron yield of BEPC LINAC-based Slow Positron Beam Line were 1.84×1010e+/s for Ta target, the slow positron yield was about 106 to 107e+/s. When the BFEL LINAC was operated under parasitic condition, the fast positron yield was 3.9×1011e+/s and the slow positron yield was about 107 to 108e+/s.
