Observations of edge radial electric field transition in LHD plasmas

M Yoshinuma, K Ida, M Yokoyama, S Murakami, A Wakasa, LHD Experimental Group2004年Plasma Physics and Controlled FusionIF 2.2出版社

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.This article was due to appear in volume 45, issue 12A of Plasma Physics and Controlled Fusion.

径方向電場の遷移を、改良された時間分解能を持つ荷電交換分光法を用いて大型ヘリカル装置において調査した。径方向電場が正から負へ変化する臨界密度は、内側シフト配位と比較して、外側シフト配位ではリップル損失が大きいために高くなることが観測され、これは新古典理論の予測と定性的に一致する。本論文は、Plasma Physics and Controlled Fusionの第45巻、第12A号に掲載される予定であった。この特集号にアクセスするには、以下のリンクを参照されたい:www.iop.org/EJ/toc/0741-3335/45/12A。
