- Abstract
We describe the concept of a subterahertz gyrotron with frequency tuning, which is based on the regime of a resonance backward-wave oscillator with a combination of an irregular low-Q cavity and a narrow-band external reflector. The simulation performed for the gyrotron at the fundamental cyclotron resonance demonstrates the possibility of creating gyrotrons with high efficiency (10–30%) ensured in a wide frequency range (about 10%). For the gyrotron at the second cyclotron harmonic, the calculations predict that a gyrotron with frequency tuning in a band about 1% can be implemented with an efficiency of 5–10%. A possible solution of a problem of the narrow-band external frequency-tunable reflector is also discussed.
