Electron Beam Bunching in High-Power Relativistic Klystrons

The authors discuss results from studying the effect 2D processes have on the bunching of electrons in high-power single-beam relativistic klystrons. Data are presented on the maximum achievable efficiency of such devices. Results are presented from a numerical analysis of the structure and magnitude of wake fields of relativistic electron bunches as a function of the degree of compression of bunches and the energy of electrons.
