Abstract：
To have a high positron yield,it is extremely important to minimize the primary electron beam radius at the positron production target. Various effects on electron beam blow-up have been analyzed.By comparing the measured beam radius with simulation,result at current BEPC positron source,some concrete effects on beam blow-up have been described. A design study on minimizing the electron beam radius at BEPC-Ⅱ positron source is given,and the ways to reach this goal have been summarized.
