Nonlinear interaction of lower hybrid wavesFunded under: FP3-FUSION 11C
Lower hybrid current drive has proved very successful in a number of experiments, with a wave spectrum corresponding to a range of resonant parallel velocities extending from thermal to relativistic velocities. This paper examines the question of how a consistent population of suprathermal electrons is generated with a launched spectrum corresponding to velocities well above the bulk of the distribution function. It is shown that a model which includes nonlinear interactions is able to produce an upshift in the parallel refractive index sufficient to drive significant current.
