摘　　要：本文介绍了波导阀门放气量和波导阀附近真空系统的真空度的关系。波导阀门放气量对速调管陶瓷窗附近的真空度有极大的影响。在计算和实验研究的基础上,我们对波导阀门的放气量进行了理论计算,按照BEPCII对速调管陶瓷窗真空度的要求改进了真空系统。Describes the relationship between the outgassing throughput at waveguide valve and the air pressure in the vicinity of waveguide valve, where the former affects extremely the air pressure in the vicinity of ceramic window of klystron. According to the numerical testing results, the outgassing throughput at waveguide valve is calculated theoretically. Then, the vacuum system is improved in accordance to the vacuum degree required for the ceramic window of the klyston for BEPC Ⅱ linac.
