Current drive via Landau damping of kinetic Alfven wave in toroidal geometry

Creators

Description

It is found that Landau-damping of low-phase-velocity (vp<<vte, the electron thermal speed) waves is profoundly affected by toroidicity. The proportion αu of the wave energy imparted to the untrapped particles significantly exceeds their numerical fraction. Computed values of αu versus vp/vte are presented. The implications of these results on low-phase-velocity-wave current drive are assessed. (orig.)
