Syntesis of the Quasi-Optimal Pitch Variation Law for the Helical TWT

Abstract

A method for designing helix TWTs is proposed on the basis of specifying the law of variation of the phase difference between the first harmonic of the current and the wave with the subsequent synthesis of the law of variation of the helix pitch. The effectiveness of the proposed method is shown, which makes it possible to obtain high values of the efficiency of the first harmonic and the technical efficiency of the device.
