Abstract

Two kinds of gyro-devices are considered: gyrotrons for material processing and tunable microwave devices for Electron Cyclotron Ion Sources. The possibility of the significant output efficiency enhancement due to energy recovery for the gyrotrons operating at cyclotron harmonics was demonstrated. The second-harmonic 24 GHz gyrotron for technology application with output efficiency of 60% was developed and tested at IAP RAS. Record efficiency was obtained by optimizing the profile of the magnetic field and using the energy recovery for the spent electron beam. Different varieties of gyro-devices providing broadband radiation (multi-frequency or fast-swept in time) with CW or average power of order of 10-15 kW and the center frequency within the range of 24-60 GHz are also discussed.
