Abstract
This study presents a channel-type multipacting cathode and employs the particle-in-cell (PIC) and Monte Carlo (MC) simulation methods to investigate the influence of various cathode parameters, including channel material, channel aperture, axial applied electric field, and initial input current on emission performance. All these parameters are found to significantly affect the output current density of the cathode and are further optimized. The optimized cathode can achieve an output current density of 380 A/cm2, significantly enhancing the output current density of the multipacting cathode and providing valuable theoretical support for the design of cathodes with high current density.
