  Term: Radial Ponderomotive Force Stabilization
  Definition: In magnetic mirror devices, use of rf waves in the neighborhood of the ion cyclotron frequency to stabilize interchange modes. The radial ponderomotive force produced by a radial gradient in the applied rf electric field opposes the destabilizing centrifugal force resulting from bad magnetic field curvature. The net particle current is in the direction that would result from field lines with good curvature, eliminating the drive for the interchange instability.
