合肥光源电子储存环束流闭轨的局部校正
-
摘要: 在合肥同步辐射装置运行过程中,发生储存环的束流轨道偏移。利用现有设备对束流闭轨的位置进行了多次测量和分析,利用测量数据计算得到校正铁强度与束流位置之间移动的响应矩阵。并利用最小二乘法计算得到三个校正铁的凸轨系数,用于束流闭轨的局部凸轨校正,取得了预期的效果。Abstract: HLS is a second generationsynchrotron light source.During itsoperation, the distortion of the electronbeam orbit was often detected. The positionof the beam orbit was measured with BPMs andanalyzed, and the response matrix, whichindicates the relationship between thestrength of the correctors(or the current of the corrector power supply)and the beamposition, also was calculated with themeasured data?
