合肥储存环二期改造工程的调试

Adjustment of the Phase Ⅱ Upgraded Program of the Hefei Electron Storage Ring

合肥光源二期工程改造后,对电子储存环光学参数进行了全面的调试和测量,新注入系统和高频系统的调试,也获得了巨大的成功,在插入八极铁和过正地补偿色品后,耦合束团不稳定性的得到了有效地抑制,从而使改造后电子储存环能积累和运行在300mA以上的流强．

After upgrade of the Hefei light source, the optics parameters of electron storage ring were adjusted and measured. Both the kicker and the RF system were reconstructed completely, and were commissioned well. The SVD algorithm is used for the global closed orbit feedback. Two methods were used to suppress the transverse coupled bunch instability. So a 300mA beam intensity is achieved.
