摘要：
An optimization methodology is put forward for the design of gridded electron gun, which pays special attention to the spacings among cathode, shadow grid and control grid. The optimization is carried out on the basis of Microwave Tube Simulator Suite MTSS and multi-physics simulation software ANSYS. Using this optimization method, the electric performance of the designed gridded electron gun under working condition has minor changes compared to the simulation results. Using the designed spacings among cathode and the grids as mounting dimensions, the unexpected contact among cathode and the grids due to thermal deformation has less possibility to occur.
