基于分裂型弯铁的储存环超周期HMBA磁聚焦结构
Storage Ring Super-Period HMBA Lattice With Split-Bend
摘要
Abstract
A storage ring super-period HMBA lattice with split-bend is proposed,which has two different types of straight sections with high and low β.Lower β at the straight sections can increase the radiation brightness of insertion devices and reduce the impact of insertion devices on the optics.And the higher β can enlarge the dynamic aperture,which is beneficial for beam injection.In this HMBA lattice,a split-bend and a quadrupole doublet are combined into a triplet-like structure,which is used to realize high and low β at the straight sections and is beneficial for emittance reduction as well.A storage ring light source with an energy of 3 GeV is designed based on this concept,with a natural emittance of 101 pm·rad.The 6D horizontal dynamic aperture at the middle of high β straight section is approximately-8～9 mm,and the horizontal and vertical β at the middle of low β straight section are less than 3.1 m.关键词
