When a microbunch with high charge traverses a curved trajectory, the curvature induced bunch self-interaction via the coherent synchrotron radiation (CSR) may cause serious increase in energy spread and emittance degradation. Recent CSR experiments carried out at CERN and Jefferson Lab both exhibit larger energy modulation and emittance growth than predicted by previous analyses and simulations. In this paper, we present our recent analysis and simulation which explain the measured enhancement of the CSR effects.
