合肥同步辐射光源的耦合度校正
-
摘要: 在合肥同步辐射储存环中由于四极铁的旋转误差和在六极铁中垂直方向的闭轨畸变等，导致电子水平和垂直两个方向的运动的耦合，耦合度达到12%（测量值）。为降低束流的横向耦合度，提高光源亮度，拟在储存环中安装斜四极铁，探讨了斜四极铁的设计及安装的方法。Abstract: Because of quadrupoles rotation errors and vertical orbit distortions in sextupoles, it will induce the coupling of the horizontal and vertical directions, and the coupling is 12% (measurement result). The skew quadruples will be installed for horizontal-vertical coupling correction in HLS. The installation method is studied in the paper.
