Abstract
It is shown that low-n pressure driven external modes in tokamaks can be fully stabilized by resistive walls in combination with sonic rotation of the plasma. The stabilization depends on the excitation of sound waves by the toroidal coupling to Alfven waves and is affected by ion Landau damping. Two-dimensional stability calculations are presented to show the gains in the beta limit resulting from this wall stabilization. (author) 4 figs., 13 refs.
