Abstract

This paper describes the imperfection and correction for the CEPC CDR lattice in the Higgs mode. The correction scheme contains closed orbit correction, optics correction and the betatron coupling correction. Two error cases with 1000 lattice seeds are studied and statistically analyzed. The dynamic aperture after correction is also studied to compare the on-axis beam injection requirement.
