Abstract

内容記述

Recent Large Helical Device (LHD) experiments revealed that the transition from ion root to electron root occurred for the first in neutral beam heated discharges, where there is no non-thermal electrons exist. The measured values of the radial electric field were found to be in qualitative agreement with those estimated by neoclassical theory. For the configuration with a magnetic axis of 3.75m, where the ion transport loss was comparable to the neoclassical ion loss, a clear reduction of ion therrnal diffusivity was observed after the mode transition from ion root to electron root as predicted by neoclassical theory. On the other hand, for the inward shifted configuration (Rax=3.6m), where the neoclassical ion loss is reduced below the anomalous loss, no change in the ion thermal diffusivity was observed.
