Nonlinear Excitation of Magnetostatic Fluctuations by Kinetic Drift-Alfven Waves

摘要

It is shown that, for typical tokamak parameters, superthermal magnetostatic convective-cell fluctuations can be nonlinearly excited by a moderate level of kinetic drift-Alfven turbulence (e.g., delta n/n sub 0 approx. 1 %). Effects on the plasma cross-field transport and the nonlinear evolution of drift-Alfven turbulence are also briefly discussed. (ERA citation 07:048734)
