Abstract：
The characteristics of the electron beam current transport in the electron gun of the electrocurtain accelerator were studied and the origin of the influence on longitudinal uniformity of beam current was analysed. The deflection of the cathode is considered under the boundary condition of perfect constraint.Then a newly designed electron gun is introduced with longitudinal uniformity of current within±10%.
