Description

Hefei Light Source (HLS) is a small and compact synchrotron light source with an electron beam energy of 800 MeV and a circumference of 66.13 m. The storage ring lattice adopts the Double-Bend Achromat (DBA) structure with 4 super periods. Considering the future upgrade of the injection system by using a nonlinear kicker (NLK), we optimize the dynamic performance of the storage ring. The optimization mainly aims at increase the dynamic aperture and beam lifetime, which helps improve the injection efficiency for the new injection scheme. While keeping the current layout of the lattice, the linear optics is also modified in order to improve its nonlinear performance. In this paper, we represent our work on the optimization of the HLS-II storage ring.
