Abstract：
Dipole field kicks arisen from the construction and alignment of the magnets may cause the particle travels away from the ideal orbit in the transport line. In this paper, orbit distortion corrections of the SSRF BTS lattice are done with the response matrix and SVD algorithm based on AT (matlab) toolbox. Study on the different correctors and BPMs placements are carried out. We also study the orbit distortion correction result which is affected by the interceptive value used in the SVD algorithm.
