Abstract

A 70 kA (qm = 5) flat-top discharge and a 120 kA (qm = 3.6) flat-top discharge with zero loop voltage are realized by 2Ωe electron cyclotron current drive (ECCD) and lower hybrid current drive (LHCD), respectively. The figure of merit of current drive is 0.03-0.06 (1019 A·W-1·m-2) for ECCD and 0.3-0.6 for LHCD. 2Ωe ECH at the q(r) = 1 surface on the high field side of the midplane is more effective in stabilizing sawteeth than on the low field side. LHCD can stabilize sawteeth, m = 1 and m = 2 MHD activities. In the full LHCD discharge, there are no sawtooth, m = 1 and m = 2 MHD activities.
