abstract = {The phenomenon of synchrotron radiation from electrons is at the core of modern accelerator based light sources. While synchrotron radiation in the far field has been well established, the self-consistent beam dynamics due to the near-field synchrotron radiation becomes increasingly important as high-brightness beams and coherent light sources are developed. Since it is difficult to diagnose the near fields in experiments, accurate and efficient numerical methods are essential to the design of these light sources. Here, we investigate several existing methods for the calculation of the radiation near fields, including the finite difference method, the Lienard-Wiechert method and a novel near-field method. We compare the accuracy and efficiency of these methods in both 1D and multi-dimensions, for both steady-state and dynamic beam trajectories, both radiation field and space charge field, as well as for both coherent and incoherent fields. We also discuss a self-similarity feature in the synchrotron radiation that can be exploited to improve the calculation.},
