给出了第三代同步辐射光源ＨＥＬＳ储存环的聚焦结构设计．在该设计中采用由不同弯转角度的弯铁组成的ＱＢＡ聚焦结构，从而得到较低的束流发射度；仔细选择它的工作点以抑制二极色品；使用多组六极铁较好进行了色品校正与谐波校正；最后使用跟踪程序进行了跟踪计算，结果表明该储存环具有足够大的动力学孔径和能量接受度
The focusing structure design of HELS storage ring of the third generation synchrotron radiation source is given. In this design, a QBA focusing structure consisting of bent irons with different bending angles is used, resulting in lower beam emission; careful selection of its operating point to suppress bipolar materials; and the use of multiple sets of six-pole irons is preferred Chromatic Correction and Harmonic Correction were performed. Finally, the tracking program was used to track the results. The results show that the storage ring has a large enough kinetic aperture and energy acceptance
