合肥光源慢加速过程中高频系统的调节
RF system adjustment in ramping process of HLS

摘要: 合肥光源是一台专用同步辐射光源,它在低能注入积累束流,然后同步地把束流加速到高能并在储存环中稳定运行。在加速过程中,粒子的同步辐射能量损失迅速增加,束流负载效应发生变化,需要相应地调节高频系统参数保持束流稳定。讨论了合肥光源加速过程中高频系统可能的两种高频系统调节方式以及高能情况下高频系统的最佳运行状态。

Abstract: HLS (Hefei light source) is a dedicated synchrotron radiation light source, where charged beam with low energy is injected and accumulated in the ring, and then the beam is synchronously accelerated to high energy and circulates in storage ring. During ramping process, with the drastic increasing synchrotron radiation energy loss of particle, beam loading is changing and appropriate adjustment of RF parameters is necessary in order to keep beam stability. In this paper, two possible RF adjustment modes for ramping in HLS are discussed and optimum RF status during operation in high energy is calculated.-
