Feasibility of using rectilinear electron beams with a low current density to amplify and generate high-power microwave radiation
Abstract
An analysis is made of the physical mechanisms which make it possible to use rectilinear electron beams with low current density (determined by the emissivity of the thermocathodes used) to amplify microwave radiation. It is shown that the use of resonance effects in periodic electrodynamic structures leads to a considerable increase in the beam/field coupling coefficient and in the gain.
