摘要：
This paper presents the results of numerical and experimental study of a Ka-band relativistic Cherenkov oscillator with average diameter of the slow-wave structure D approximate to 2.6 lambda. (lambda is a wavelength). The combined mode selection including the diffraction loss in the electron diode was applied. The high-current accelerator SINUS-200 provided the thin-walled annular electron beam in the range of voltages 350-420 kV and currents of 2.9-3.8 kA at pulse width of 10 ns. The generation of 2.5-3-ns pulses at the central frequency 36.4-36.8-GHz and 400-600-MW output microwave peak power was realized. The corresponding efficiency of 42% +/- 5% in power conversion has been obtained.
