Based on the self‐consistent nonlinear theory, a W‐band continuous wave 30 kW fundamental harmonic gyrotron oscillator is designed and simulated. With a 30.0 kV, 3.0 A electron beam, the output power of more than 35 kW is obtained and the maximum electronic efficiency is equal to 40.3%. The effects of electron beam voltage, beam current, magnetic field intensity, guiding center radius, and velocity spread on electron efficiency and output power are analyzed in detail. In addition, the images of correlative electron clustering states in the process of beam‐wave interaction are presented intuitively.
