Powerful relativistic generators on rectilinear electron beams with electrodynamic filters at the ends

Abstract

This paper presents the results of the calculations of high-power generators of microwave radiation on the rectilinear electron beam on resonators with electrodynamic filters at the ends of the resonators. The results of calculations of high-power generators of microwave radiation on rectilinear electron beam on resonators with electrodynamic filters at the ends of the resonators are presented. The methodology for calculating processes in the irregular waveguide is based on the ideas of A. G. Sveshnikov, based on the coordinate transformation method, which allows searching for a solution of the excitation problem of the irregular waveguide by expanding this solution into the system of basic functions of the regular waveguide. allows you to search for a solution to the excitation problem of an irregular waveguide by expanding this solution into a system of basic functions of a regular waveguide. This allows reducing the 3-dimensional problem to the one-dimensional one allows us to reduce a 3-dimensional problem to a one-dimensional one, which significantly reduces the amount of computation and increases the accuracy of the solution. The calculations are carried out using the computer program Gyro-K. The presence of electrodynamic filters at the ends of the waveguide makes it possible to increase the quality factor of the resonator and reduce microwave radiation to the cathode region. We demonstrate that the power of such generators may reach 21 MW, which may provide effective suppression of the electronic devices of the alleged enemy. Kolosov S. V., Batura M. P., Shatilova O. O.
