The H-mode-like discharge was triggered by changing the PNBI from 9 MW to 5 MW in a density range of 4-8 × 1013 cm-3, followed by a clear density rise, ELM-like Hα bursts, and a reduction of magnetic fluctuation. These H-mode-like features vanished with a small radial movement of the 1?1 surface.}, title = {H-Mode-Like Discharge under the Presence of 1/1 Rational Surface at Ergodic Layer in LHD}, volume = {Vol. 80}, year = {2004} }
