Abstract

Improvement of an enhanced confinement state in a high poloidal beta (β_p) regime without sawtooth activity has been achieved in JT-60U. A confinement mode has been demonstrated where both the edge and the core confinement are improved. The attainable β_p was also extended to higher values in this improved mode, because of its broader pressure profile. As a result of the improvement in confinement and in attainable β_p, the highest value of the fusion triple product has been extended by a factor of 2.5 over that achieved in the 1992 experiments; it has reached (1.1 ± 0.3) × 10²¹ m^-3.s.keV with a central ion temperature of about 37 keV. The D-D neutron emission rate has also been doubled in these experiments and has reached (5.6 ± 0.6) × 10¹⁶ s^-1.
