Abstract
Using lower hybrid current drive (LHCD), improved confinement has been achieved on HT-6B tokamak. The particle confinement time was increase d by 2-6 times and the plasma-stored energy was doubled. Only obtainab le in an electron density window of 0.3x10(13)-1.5x10(13) cm(-3), the improvement was accompanied by suppression of the fast fluctuations an d increment of the gradient of edge electron temperature with very low power threshold. An analysis shows that the improvement might be poss ibly caused by certain energetic electrons produced by LHCD.
