The paper describes simulation and design of a W-band gyrotron oscillator operating in the circular TE03 mode at the third cyclotron harmonic. A self-consistent nonlinear code and a particle-in-cell (PIC) software were used to investigate the beam-wave interaction. Results of PIC simulations show that the gyrotron oscillator can generate peak power of 12kW at 93.57GHz when utilized a 35kV, 4A, ν ⊥...
The paper describes simulation and design of a W-band gyrotron oscillator operated in TE03 mode at the third cyclotron harmonic.
