摘要
合肥同步光源的现有注入凸轨由 3块冲击磁铁产生 ,不同的运行模式具有不同的凸轨 .为了改变这种凸轨参数与储存环参数的相互依赖 ,提出采用集中布局的方案 ,即在注入长直线节形成注入局部凸轨 .由于HLS的注入长直线节很短 ,需要冲击磁铁为束流提供较大的偏转角度 .为此 ,本文研究了采用辅助直流凸轨的方案 ,以减小对冲击磁铁强度的要求 ,并分析该注入系统对储存环动力学孔径的改善 .
Hefei synchrotron Light Source(HLS) presently has three kickers for injection,and different lattices will form different shapes of bump orbits In order to relieve the dependence between bump and lattice,a compact injection scheme,in which four kickers are located at the same straight section,is proposed.Because the straight section for injection is too short,it needs kicker to produce strong magnetic fields.This paper looks into the possibilities of using orbit correcting trim coils to make assistance DC bump orbit to reduce kickers strength.The different schemes and their advantages are discussed.
