Abstract

An efficient current drive synergy between lower hybrid and ion-ion slow modes was identified recently. In this paper the enhancement of lower hybrid current drive in the presence of wave converted ion-ion slow modes is discussed using the one-dimensional quasilinear equation. The special case in which the slow mode resulting from conversion in a deuterium-hydrogen mixture is absorbed by low energy electrons is considered in detail. The one-dimensional theory of current drive by Landau damped waves is presented and a general formula for the parallel distribution for two ion resonance converted modes is derived. Finally, some numerical results are discussed to identify salient features of the current enhancement.
