Numerical Simulation of Electron Bunching Characteristics of Inductive Output Tube

In this paper, in order to study 650MHz inductive output tube, according to the basic principles of electrodynamics, the influence of the gap and field strength between the cathode and grid, the bias voltage of grid and frequency offset on the modulation density of electron beam is simulated and analyzed, and the verification is carried out by using the three-dimensional electronic optics software.
