Plasma stability in the presence of mass flow
The ideal stability of cylindrical plasma with mass flows is studied using the guiding centre plasma (GCP) model of Grad. The results are significantly different from those obtained in magnetohydrodynamics (MHD). The kinetic treatment of the parallel motion in GCP removes the resonant interaction with slow magneto-acoustic waves and the loss of stability that results in MHD for near sonic flows. In GCP, flows can be stabilizing for the local modes depending on the profiles, but external kink modes are always destabilized by flow if the rotation speed vanishes at the plasma boundary.
