Steady state plasma performance on JT-60U

Naito, Osamu; JT-60 Team

Recent results from JT-60U on high performance experiments and studies on steady state plasma are presented. High fusion performance of $n_{D}(0) tau_{E} T_{i}(0) = 1.1times 10^{21} mathrm{m}^{-3}$ s keV, $S_{n} = 5.6 times 10^{16} mathrm{s}^{-1}$ , $Q_{DT} = 0.6$ , $T_{i}(0)$ = 40 keV has been obtained in the regime named ''high- $beta_{p}$ H-mode''. By intensive survey on pressure/current profile control, beta limit has been substantially expanded: $beta_{p} le 4.3$ , $beta_{N} le$ 4.0%mT/MA. As a result, up to 10 seconds of quasi steady state high confinement discharges, with a substantiall bootstrap current fraction, have been experimentally demonstrated. Up to 3.6 MA of plasma current has been driven by LHCD. In low current ( 1.2 MA), full non-inductive current drive has also been achieved by NB and NB+LHCD.
