  • In view of the uneven distribution of magnetic field in the devices caused by the metal surface eddy current in the high-current pulse electron beam diode, the surface treatment effect of the electron beam irradiated material is not good, and the double structure design of the multi plate steel connecting inner wall with the glass outer wall is proposed. Based on the finite element simulation software, the magnetic field and eddy current of the electron beam system are numerically calculated. The influence factors of the eddy current and the influence of the eddy current on the magnetic field of the electron beam source are analyzed. The result shows that the design of the new dielectric wall structure can effectively reduce the effect of eddy current on the electron beam. The analysis provides a theoretical basis for eliminating the influence of induction eddy current on the magnetic field of diode.
