Full-Particle Simulation on Beam Electron Plasma in Linear Confinement System

Abstract

Three-dimensional full particle simulation is performed on the electron beam plasma electrostatically confined in a linear chamber. Sausage instability and kink instability occurred within 1 µs from the initial state, and a twisted structure is also observed. The density distribution flattened with time and resultantly diffused in the radial direction. However, large scale collapse phenomenon until the beam plasma disappeared is not observed.
