工作点反馈系统对同步辐射光源运行稳定性的提升(英文)
发布时间:2021-08-07 18:00
上海同步辐射装置(SSRF)储存环上目前已经安装了十台插入元件(IDs)。在用户时间,插入元件的间隙被反复地调整以进行科学实验。虽然使用了插入件前馈系统,但依然存在扰动束流光学的残余四极场,它会导致束流横向振荡工作点的变化,进而影响机器的性能和同步辐射光亮度的稳定。为此,我们研发了一个工作点反馈系统来解决这个问题,并且已经在上海光源储存环上投入了运行,在两周左右的运行周期内,工作点的稳定度达到了±0.001。这个反馈系统还有另一个重要功能,即可以根据监控反馈系统校正电流的变化趋势来判断二极磁铁电源和四极磁铁电源是否存在慢漂问题。为了验证这个工作点反馈的可行性,我们对使用反馈前后几周的束流参数进行了比较,包括储存环注入效率、束流寿命、水平方向束斑尺寸以及β函数的变化情况(beta-beatings)。
