Preliminary study of the wavelength shifter effect in SRRC storage ring

The possibility of installing a superconducting wavelength shifter was discussed in SRRC. After surveying and comparing, magnet of one full strength pole and two half strength poles, with peak field of 7.5 tesla, was chosen for the feasibility study. Due to the space constraint, the wavelength shifter will not installed in the straight section middle. This paper reports the perturbation on lattice of the chosen wavelength shifter and the restoring from its perturbation. Effect on the ring is also investigated form the dynamic aperture point of view.
