Abstract
Radial transport in non-neutral plasmas driven by a rotating wave field is examined in terms of the drift-kinetic Vlasov equation. It is shown that the radial flux is generated by the E×B drift of resonant particles subject to Landau damping in the axial dynamics. The rate of change in the canonical angular momentum associated with the radial flux is equal to the torque resonantly exerted by the azimuthal component Eθ of the wave. The absorbed wave energy is shared between the axial kinetic energy of the particles and potential energy of the charged particle system. The basic idea of this model may be extended to a scenario that the radial flux is generated by any other dissipative processes that shift the phase relation between the wave and the particle orbits.
