Description
H-mode production and confinement have been studied in JT-60U, for a wide range of plasma parameters (Bt = 2-4 T, Ip = 1-4 MA, PNBI = 5-25 MW). A confinement enhancement factor over the ITER power law of up to 2.2 has been obtained in 4.2 T H-modes with wall conditioning and discharge optimization. A maximum plasma stored energy of 7.7 MJ, a fusion triple product of ni(0)Ti(0)τE of 2.5 x 1020 keV·s·m-3, a maximum ion temperature of 32 keV and a maximum electron temperature of 9 keV were obtained in the hot ion H-mode regime. Progress has also been made in understanding the plasma confinement in the L-mode and ohmically heated plasmas, and factors such as isotope dependence, current profile effect, high aspect ratio confinement, thermal confinement scaling and ion transport anomaly have been investigated.
