Cold-Fluid Model of Resistive Instabilities on Intense Relativistic Electron Beams.

Abstract

Resistive instabilities with azimuthal mode numbers m = 0 and 1 are studied on intense, relativistic electron beams. An exact cold-fluid model of the beam is used, and the background is modeled by a scalar conductivity. The effects of the beam profile, the width of the conductivity and return current profiles, and the magnitude of the return current fraction are considered for beams in the 10-100 kA range with gamma = 100. Some results for modes with m = 2 and 3 are also presented. (Author)
