Research progress on JT-60U in advanced steady-state operation

Naito, Osamu

Fusion Technology 1996, Vol.1, p.215 - 220, 1997/09

Recent research progress on JT-60U in advanced steady-state operation is presented. High fusion performance of $Q_{DT} > 0.6$ has been obtained in negative magnetic shear plasmas as well as in high- $beta_{p}$ H-mode. A negative shear discharge is shown to have enhanced core confinement. Its sustainment and compatibility with radiative divertor are also explored. Stability and confinement are improved in high triangularity operation and a noninductive discharge with high integrated performance has been achieved. The installation of negative-ion-based neutral beam injection system on JT-60U has been completed and beam injection into plasmas has been started. A preparation for the modification of the present JT-60U's open divertor to a W-shaped semi-closed divertor, and a conceptual design and R&D for JT-60 Super Upgrade are in pregress.

Steady state plasma performance on JT-60U

Naito, Osamu; JT-60 Team

Plasma Physics and Controlled Fusion, 35(Suppl.B), p.B215 - B222, 1993/12

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.
