| Abstract: | A structure of complex cavity with gradual transition is employed in the second-harmonic gy-rotron is designed with the theory of beam-wave interaction, and a numerical simulation of the structure is made in this paper. The 94 GHz corrugated waveguide mode converter is optimized using corrugated waveguide structures and different phase re-matching techniques. The gyrotron with Complex Cavity Op-erating at the Second Harmonic is developed, the experimental results show that the pulse output power of 115 kW and the average output power of 3 kW at 94.2 GHz with 26% efficiency, the beam voltage is 50 kV and beam current is 8.8 A with magnetic field 1.56 T. |
