摘要

A cylindrical carbon pellet with a size of 1.0 mm Φ * 1.0 mm~L was injected into low-density (n_e = 0.3-0.5 * 10~(13) cm~(-3)) neon-seeded NBI plasmas of the Large Helical Device (LHD). When the two NBI beam pulses were delayed just after the pellet injection, a large increment of central ion temperature up to 5 keV was observed with the appearance of a peaked density profile (n_(e0)/ ～ 2.5) and enhanced toroidal rotation speed up to 35 km/s. Improvement of the ion transport is expected with the suggestion of a new operational scenario for confinement improvement in the LHD.
