Abstract:
For the Phase 2 of HLS (Hefei Light Source)Project, many sextupoles and octupoles have been installed in the machine to improve the operation condition. These nonlinear elements will introduce nonlinear effects to the beam dynamics. In this paper, we apply Frequency Map Analysis to the HLS ring. By analyzing the resonance lines on the tune map, we find that the calculated lattice of GPLS mode lies on the weak chaotic zone, and the operating mode is better.
