摘要: Progress of JT-60U experiments during last two years are summarized in this paper. After the achievement world record fusion triple product, shifted to extension operating regimes such as high performance quasi steady-state ELM'y H-mode, full CD with a large bootstrap fraction, /spl beta//sub N/ operation, triangularity and reverse shear operations. We also accumulated database for understanding ELM behaviour solve our present difficulty demonstrate plasma at (edge) density regime achieve cold dense radiative divertor enhanced confinement. demonstrated an effective He ash exhaust H-mode which is critical physics R&D issue ITER. Extensive studies various disruptions were made methods avoid disruption proposed.
