Trapped Particle Asymmetry Modes in Non-Neutral Plasmas

Abstract

Novel trapped particle asymmetry modes propagate on cylindrical electron columns when axial variations in the wall voltage cause particle trapping. These modes consist of E x B drifts of edge-trapped particles, partially shielded by axial flows of interior untrapped particles. A simple theory model agrees well with the observed frequencies and eigenfunctions; but the strong mode damping is as yet unexplained. These modes may be important in coupling trap asymmetries to particle motions and low frequency E x B drift modes.
