Optimization of the cavity of a second-gyroharmonic continuous-wave gyrotron with an operating frequency of 258 GHz

  • Published:
Radiophysics and Quantum Electronics Aims and scope

We present the results of numerical studies of the processes in the cavity of a continuous-wave gyrotron operated at the wavelength λ = 1.16 mm (operating frequency of 258 GHz) and having an output power of 100–200 W. Limitations for the choice of the working mode, which are posed by the system of electron beam formation, and the influence of parasitic modes synchronous with the electron beam at the first and second harmonics of the cyclotron frequency are considered. Optimization of the cavity profile is performed. The maximum efficiency and the radiation ower are determined for an accelerating voltage of up to 15 kV and an electron beam current of up to 0.5 A.
