A paired APPLE-II type Ellipsoid Polarized Undulator（DEPU）has been installed in the SSRF storage ring which can be mechanically switched between two undulators with difference period length. One of them get notable effects on the optics including CODs, tune, coupling and dynamic aperture. We report in this paper, feed forward tables of correctors, quadrupoles and skew quarupoles are used for the optics correction and sextupole optimization is used for the dynamic aperture recovery.

For traveling wave accelerating structures, the tuning method assisted by bead pull technique based on non-resonant perturbation field distribution measurement has been widely used. Long periodic traveling wave deflecting structure, which operating at HEM11 mode, is difficult to use non-resonant perturbation method, and a improved method has been developed for measuring and tuning by "cage" type perturbing object at SINAP. The measurements on x-band traveling wave deflecting structure are presented in this paper.
