THE SIMULATION AND ANALYSIS OF SECINDARY EMISSION MICROWAVE ELECTRON GUN

Several new approaches for producing high-current, short-duration pulses of electron beams were reviewed briefly in this paper. The paper presents mainly the simulation and analysis of a secondary emission microwave electron gun. The movement of electron in microwave electric field was simulated and the self-bunching process of the secondary emission electrons in the gun was also proved. Some factors that can affect the secondary electrons multipacting and amplifying have been studied.
