Abstract

The possibility for driving current in large tokamak plasmas using the fast magnetosonic wave is analysed in terms of linear propagation-absorption, and also in terms of quasilinear absorption through an Hamiltonian analysis of the wave-particle interaction. The tokamak geometry is shown to influence strongly the capability for the fast wave to sustain a significant part of the toroidal current. Synergetic effects with other scenarios are also discussed.
