Abstract
Improvement of an enhanced confinement state in a high poloidal beta ( beta(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 beta(p) was also extende d to higher values in this improved mode, because of its broader press ure profile. As a result of the improvement in confinement and in atta inable beta(p), the highest value of the fusion triple product has bee n extended by a factor of 2.5 over that achieved in the 1992 experimen ts; it has reached (1.1 +/- 0.3) x 10(21) m-3.s.keV with a central ion temperature of about 37 keV. The D-D neutron emission rate has also b een doubled in these experiments and has reached (5.6 +/- 0.6) x 10(16 ) s-1.
