The lattice design of the HELS storage ring for a third generation synchrotron light source is presented . To achieve low emittance , a kind of modified Quadrupole Bend Achromat ( QBA ) lattice using bend magnets with different bending angles is adopted .
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；
