Estimation of the Focusing Magnetic Field in High-power Multibeam Klystrons with Electron Beam Dynamic Defocusing Factor

Abstract

A technique is proposed and the distribution structure of the longitudinal component of the magnetic field induction in the magnetic focusing system of a high-power multibeam klystron is found, which allows the electron beam to be transported with minimal losses in the drift tube, taking into account changes in the beam velocity in the gaps of the resonator electrodynamic system.
