Stability of magnetohydrodynamic equilibria with flow in the presence of a resistive wall

S. N. Bhattacharyya

Open publisher page 2 citations

Abstract

The effect of a resistive wall on the stability of a magnetohydrodynamic equilibrium with flow is examined. Gyroscopically stabilized negative energy modes are shown to become unstable in the presence of a resistive wall. An estimate for the growth rate is obtained. The effect of this destabilization on the limits on the safety factor and the plasma beta for a rigidly rotating plasma column are studied.
