High Intensity Electron Beam Propagation between Two Plane Conductors and Its Implications for Collective Ion Acceleration.

摘要

This paper examines the properties of a high intensity relativistic electron beam propagating between two grounded plane conductors, with particular emphasis on the implications for collective ion acceleration. The steady-state and time averaged equilibrium properties are obtained analytically, by employing a one-dimensional model. Numerical integration of pulsed-beam propagation is shown to result in an oscillatory state around the time averaged equilibrium solution. Based on this investigation, a model of linear beam collective ion acceleration is presented. It is shown that within a few nanoseconds of acceleration time, the ion kinetic energy can be increased to more than ten times electron energy. (Author)
