Lattice Upgrade of the SSRF Storage Ring | |
|
||
| Shanghai Synchrotron Radiation Facility (SSRF) will implement its Phase II beamline project in the near future. In this project, two long straight sections of the SSRF storage ring will be installed with dual-canted insertion devices. Double-mini-βy optics in the long straight section is designed and optimized in order to obtain high brightness and good machine performance. Lattice upgrade with super-bend is also proposed. Local achromatic for superconducting wiggler is necessary to suppress emittance growth. The lattice upgrade and beam dynamics of the SSRF storage ring with these considerations are presented in this paper. | ||

| Impedance is very important for the beam instability in a storage ring. More and more small gap In-vacuum IDs are installed in the SSRF storage ring and introduced local transverse impedance. Since the beams sees the impedance as quadrupole whose strength depends on the beam current, LOCO is used for the impedance distribution. Impedance disribution is determined by phase advance and quadrupole strengths slops. | ||
