Description

Transition phenomena of the radial electric field are investigated using charge exchange spectroscopy with an improved time resolution in large helical device (LHD). The critical density, where the radial electric field changes from a positive to negative value, is observed to be higher in the outward shifted configuration because of a large ripple loss than that in the inward shifted configurations, which qualitatively agrees with the predictions of neoclassical theory
