【摘要】 介绍基于BEPCLINAC和BFELLINAC（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BEPCLINAC和BFELMNAC运行于兼容模式时分别为184×1010/s和3．9×1011/s。若慢化体慢化效率在10-4量级，基于BEPCLINAC和BFELLINAC慢正电子束的慢正电子产额分别为106－107/s和107－108/s。更多还原

【Abstract】 A Monte-Carlo simulation about the positron source used on the BEPC andBFEL LINAC-based slow positron beam lines was reviewed. The results showed thatwhen the BEPC LINAC was operated under parasitic condition, the fast positronyield of BEPC LINAC-based Slow Positron Beam Line were 1.84 ×1010e+ /s for Tatarget, the slow positron yield was about 106 to 107e+/s. When the BFEL LINAC wasoperated under parasitic condition, the fast positron yield was 3.9 × 1011e+/s and theslow positron yield was about 107 to 10°e+/s.更多还原
