Destabilization of Alfven-resonant modes by resistivity and diamagnetic drifts

Creators

Description

The existence of unstable resistive drift-Alfven modes is shown. The modes, driven by nonuniformities in the diamagnetic drift frequency, are unstable even when the associated purely resistive mode is stable. The growth rate has a weak, eta/sup 1/4/, dependence on resistivity. Because of their large growth rates, they may play an important role in tokamak confinement. 13 refs., 3 figs
