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.

Notes

  1. Calculations were performed by T.M. Sapronova.

  2. The law of the cross section or compression conservation during retardation is well known in exact solutions of the beam equations describing the flow from a flat cathode or a cathode in the form of a logarithmic spiral [18, 20].
