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。
This article describes the relationship between the deflation rate of the waveguide valve and the vacuum level of the vacuum system near the waveguide valve. Waveguide valve deflation of the klystron ceramic window near the vacuum has a great impact. Based on the calculation and experimental research, we theoretically calculate the deflated volume of the waveguide valve and improve the vacuum system according to the requirements of BEPCII on the vacuum degree of the klystron ceramic window.
