摘要

Recent lower hybrid current drive(LHCD), and heating(LHH) experiments on JT-60 are reported. The current drive product of nBAR(e)R(p)I(RF) approximately 12.5x10(19)m-2MA was achieved at the LH power of approximately 4.5MW, and the CD efficiency, the energy confinement, the global power balance and the heat load on divertor plates were investigated in high power LHCD plasmas. Nearly steady state H-mode discharges were found during LHCD with two different frequency injections. Sawtooth suppression in NB heated plasmas by LHCD have shown an improvement in confinement near the plasma center. Parametric instabilities in LH heating experiments were significantly reduced by increasing the plasma current, and the stored energy increased linearly with heating power of up to approximately 9MW at nBAR(e) approximately 7x10(19)m-3 and I(p) = 2.75MA. Parametric instabilities near the plasma edge in the ion heating regime were also reduced in peaked density plasmas produced by pellet injection, and LH waves increased the central plasma pressure at n(e)(0) > 1.4 x 10(20)m-3.
