合肥同步辐射储存环的高频工作模式

Work mode of high frequency system in HLS storage ring

在测量高频系统基本参数的基础上，对合肥同步辐射储存环高频腔的大失谐角工作模式进行了分析，指出其不合理性和危害性，提出并成功地试验了投入控制环路，在高腔压、最佳失谐角下注入束流及升能的新的高频工作模式。

The high-frequency parameters of HLS were measured and the disadvantages of the originally accepted work mode with large tune-out angles for the highfrequency system were analyzed. Then a reasonable mode with opthoum tune-out angle and higher cavity voltage was proposed and tested successfully.
