| Abstract: | 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. |
