From Recent Results in JT-60 Heating Experiments

Abstract

During the last several month of JT-60 operation in 1987, experiments in hydrogen plasmas have been undertaken with up to 3.2MA of plasma current on limiter discharges. The maximum electron density of 13 × 10¹⁹m^-3 and the energy confinement time of 0.15-0.18 sec were obtained with heating power of 13-20MW. The total plasma stored energy of 3.1MJ, and Re (0) τ_E of 1.4-1.8×10¹⁹m^-3sec were achieved. Many short periods of H-mode phase are found in outside X-point divertor discharges with NB or NB+RF (LH or IC) heating power of more than 16MW and electron density of 2-4.5×10¹⁹m^-3.
