Abstract

Abstract—Based on the theory of high-density electron flows with the elliptical current tubes, a model of a ribbon beam from a shielded cathode in the case of emission in the ρ mode has been built. Algorithms of formation of high-compression flows passing into the Brillouin mode without oscillations with preserved elliptical cross section not rotated or strained have been developed.
