Trapped-Particle Modes and Asymmetry-Induced Transport in Single-Species Plasmas
Abstract
A new asymmetry-induced transport mechanism in pure electron plasmas is shown to be proportional to the damping rate of the corresponding trapped-particle mode, with simple scalings for all other parameters. This transport occurs when axial particle trapping exists due to variations in the electric or magnetic confinement fields. This new transport is strong for even weak unintentional trapping (δB/B~10-3), and may be prevalent in transport experiments with magnetic or electrostatic θ asymmetries.
