Analysis of Copropagating Electron Beams Interaction in a Smooth Waveguide
Linear theory methods of the coupled spacecharge waves for copropagating electron beams considering coefficients of electron interaction and a reduction of plasma oscillations are developed. Interaction of copropagating electron beams promising to amplification of microwaves in electron mode regimes to create devices of millimeter and submillimeter wavelength ranges. Equations of the coupled waves are written down and solutions of the dispersive equation in coupling regime of three and four waves are received. Large signal modes are investigated within model of large particles which has carried out the trajectory analysis of interaction processes of two copropagating electron beams with differ energy. Features of interaction modes with the gain and no gain waves are considered.
