摘要：
We present the calculation results for the bandwidth of smooth mechanical tuning of the generation frequency in a gyrotron with a coaxial cavity. The tuning is based on moving a cone-shaped coaxial rod along the device axis to vary the eigenfrequencies of the cavity. The use of an internal conductor with an impedance surface allows reducing the thermal load on it. The calculation results show that it is possible to tune the operating frequency of the oscillator by 3–4% at frequencies up to 330 GHz for an output power of about 10 kW in the continuous-wave operation regime.
