Thermal Cavity Calculation of 38GHz Extended Interaction Oscillator

In this article, an EIO cavity with a frequency of 38GHz is designed and the particle simulation is shown. Through numerical calculation and computer simulation, the results of particle simulation is also shown in this article. When the voltage is 20.4kV, the current is 1.35A, and the longitudinal magnetic field is 0.3t, the average output power is 9.3kW, and the energy conversion efficiency is 33.8%。This research is of great significance for the development of millimeter wave vacuum devices.
