Abstract

The invention discloses a planar multi-channel slow wave structure. By processing four metal slow wave lines which have the same transmission direction, are sequentially arranged and aligned in parallel on a medium substrate, the same working voltage is simultaneously loaded, and the same electron beam is used. Among the four metal slow wave lines, the identical slow wave lines in pairs are connected in series in an end-to-end manner to form two sets of the metal slow wave lines connected in series, so that an amplified electromagnetic wave signal is returned to the start place of beam-wave interaction, namely, the position before the electron beam deceleration, and the beam-wave interaction is performed again to achieve the purpose of further amplifying the electromagnetic signal, therebysignificantly increasing the gain. At the same time, since the two sets of the metal slow wave lines connected in series operate in different frequency bands, the working bandwidth can be significantly improved without affecting the efficiency of the beam-wave interaction. Compared with the scheme using multiple traveling wave tubes, the planar multi-channel slow wave structure of the invention can greatly reduce the equipment size.

Description

technical field [0001] The invention belongs to the technical field of vacuum electronic devices, and more specifically relates to a planar multi-channel slow wave structure in vacuum electronic devices such as traveling wave tubes and klystrons. Background technique [0002] Vacuum electronic devices are a class of power amplifiers that convert the kinetic energy of high-energy electron beams into electromagnetic wave energy after the interaction between high-energy electron beams and electromagnetic wave signals, including traveling wave tubes, klystrons, return wave tubes, and gyrotrons. The slow wave structure is the core component of the traveling wave tube, and its structure determines the main working performance of the traveling wave tube. In a slow wave structure, the electromagnetic wave phase velocity is less than the speed of light in vacuum. The electron beam can be accelerated to slightly greater than the phase velocity of the electromagnetic wave by a suitabl...
