Abstract

An experimental investigation of the generation in a 8-mm wavelength range in a one-sectional overmoded slow-wave structure (SWS) near the high-frequency boundary of the TM₀₁-mode passband versus the SWS length and electron beam geometry has been made. An optimization of a two-sectional multiwave Cerenkov generator has been carried out on the basis of the obtained results. The generation of the radiation with a 8.84-mm wavelength has been realized. The power radiated into the atmosphere was 500 - 600 MW at the efficiency of 6 - 7%, 20-ns pulse length at a half-maximum, and spectrum width being not over 0.5%. The possibility to obtain the linearly polarized radiation with the power to 150 MW in a one-sectional SWS under condition of using a hollow electron beam with an ellipsoidal profile has been shown.
