摘要: 研究了合肥光源（HLS）储存环光学参数和聚焦结构参数间的微分关系，在改变三个输运线上游的光学参数时，计算和分析了下游各个聚焦结构参数。并且利用获得的表达式，结合合肥国家同步辐射实验室的实际改造需要，给出在满足插入件运行条件的情况下的各个聚焦结构参数。设计了能降低Wiggler插入点处横向振荡振幅函数的Lattice结构。Abstract: In this paper, the differential relation between optic parameter and lattice parameter in electron storage ring of HLS is presented; the lattice parameter at downriver is evaluated and analyzed when the optic parameter at upriver is changed. Using the expression the lattice parameters is calculated when the Wiggle is inserted, satisfying the need of the improment of NSRL (National Synchrotron Radiation Lab.). Considering this relation, the lattice is designed renewedly in order to reduce the b function where the Wiggler was inserted.
