Low-frequency fluctuations of the Ohmically heated plasma in the Proto-Cleo torsatron

T.A. Casper, J.L. Shohet1980年被引用 6Nuclear FusionIF 3出版社

Low-frequency (f<500 kHz), turbulent density fluctuations have been observed in the Ohmically heated plasma of the Proto-Cleo torsatron. The power density spectrum indicates a spectral decay of the form f−2.5 with no coherent modes present in the observed band. Phase spectral characteristics indicate wave number estimates which vary in magnitude and direction consistent with drift-wave phenomena. Parallel wave numbers are coupled proportionally to the shear.

低周波数(f<500 kHz)の乱流的密度揺動が、Proto-Cleo torsatronのオーム加熱プラズマにおいて観測された。パワー密度スペクトルは、観測帯域内にコヒーレントモードを伴わないf−2.5の形のスペクトル減衰を示す。位相スペクトル特性は、ドリフト波現象と一致する大きさと方向が変化する波数推定値を示す。平行波数はシアに比例して結合している。
