Phys. Rev. Lett. 89, 245001 (2002) [4 pages]Trapped-Particle Modes and Asymmetry-Induced Transport in Single-Species PlasmasReceived 2 August 2002; published 25 November 2002 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. © 2002 The American Physical Society URL:
