  In the SSRF Phase-II beamline project, a Superconducting Wiggler (SW) will be
installed in the electron storage ring. It may greatly impact on the beam
dynamics due to the very high magnetic field. The emittance growth becomes a
main problem, even after a well correction of the beam optics. A local
achromatic lattice is studied, in order to combat the emittance growth and keep
the good performance of the SSRF storage ring, as well as possible. Other
effects of the SW are simulated and optimized as well, including the beta
beating, the tune shift, the dynamic aperture, and the field error effects.
