Abstract
Lower hybrid current drive (LHCD) efficiency in the HT-7 tokamak is observed to increase about 30% with ion Bernstein wave (IBW) heating. The current drive efficiency as high as 0.48×1019Am−2W−1 has been reached in HT-7 thanks to an LHCD/IBW synergy. The IBWs are significantly coupled to the fast electrons produced by the lower hybrid waves, thus results in higher fast electron photon temperature in the combined LHCD + IBW scenario. The interaction of LHCD + IBW improved current drive efficiency.
