Finite Geometry Effects on the Stability of a Charged Beam Propagating through a Relativistic Annular Electron Beam.

Abstract

Finite geometry effects on the stability properties of a charged beam propagating through an intense relativistic annular electron beam has been studied. The stability of the system under transverse oscillation has been examined in detail in a parameter domain pertinent to the Collective Particle Accelerator, current under development at the Naval Research Laboratory. Both the normal mode and the convective aspects of this instability have been investigated. Depsite a substantial temporal growth rate as a predicted by the normal mode approach this instability does not prevent successful acceleration of a portion of the axial beam. Thus the transverse oscillation is not fatal to the CPA operation. (Author)
