For a bunch train with a length in the 100nm range, spacing of 1um, and energy in the hundred MeV range, the action angle of the space charge force is estimated by r/γ. The space charge effect of the mirror current loop formed in the wall with a scale of 1cm will have a sustained effect on approximately dozens of microbunches behind the source particle. The strength of the interaction between such bunches and the potential instability it may cause needs careful evaluation. At the same time, the effect of the space charge inside a single bunch due to space charge effect also needs to be considered. We reorganized the lowest-order longitudinal wakefield under non-extreme relativistic conditions, and modified the inconsistent part in the theoretical derivation in some essays of the lowest-order transverse wakefield. We present the modified theoretical results and analysis. The action area are then divided into three parts. It lays foundation in future research.
