| Abstract |
The upgrade project of Hefei Light Source (HLSII) has successfully reduced the natural emittance of the electron beam to lower than 40 nm·rad at 800 MeV with five insertion devices installed. To provide enough straight sections for these insertion devices, the lattice structure has been changed to four double bend achromatic (DBA) with two super-periods from the former four triple bend achromatic (TBA). These different types of the insertion devices can greatly improve the performance of the light source, but simultaneously they can also influence the dynamics of the electron beam in the storage ring. Especially they can bring the distortion of the linear beam optics seriously. In order to make sure the stability and the quality of the beam meeting the design goal, the effect of these insertion devices must be compensated. In this paper, a direct compensation method is applied for the wiggler in the HLSII storage ring with the particle swarm optimization.
