A 0.22-THz frequency-tunable gyrotron with transverse sliced cavity has been developed and tested in TRC-UESTC. The proof-of-principle experimental results indicate that radiation frequency can be varied over a 1.39 GHz range from 222.903 GHz to 224.288 GHz by adjusting the operating magnetic field. During the frequency tuning, the maximum output power was 2.85 kW with an efficiency of 5.5%. Compared with previous results of a normal cavity without transverse slices, it is demonstrated that transverse slices can suppress the mode competition and broaden the frequency tuning range. This mechanism is beneficial to the future development of high-power terahertz gyrotron.
