Coupling between long-range toroidal correlations and radial transport in the TJ-II boundary plasma

TJ-II is equipped with two probe systems that allow the simultaneous measurement of the radial and toroidal characteristics of the boundary plasma fluctuations with high temporal resolution. The interplay between long-range toroidal correlations, local cross-field particle transport and radial structure of the edge fluctuations has been investigated. Experimental evidence is presented that both the radial correlation and the turbulent particle transport are reduced in the region dominated by zonal flows (ZFs). Experimental findings show the key role of ZFs in the edge plasma transport regulation.

TJ-IIには、境界プラズマの変動の径方向およびトロイダル方向の特性を高い時間分解能で同時に測定できる2つのプローブシステムが装備されている。長距離トロイダル相関、局所的な横断粒子輸送、およびエッジ変動の径方向構造の間の相互作用が調査されている。実験的証拠により、帯状流(ZF)が支配的な領域では、径方向相関と乱流粒子輸送の両方が低減することが示されている。実験結果は、エッジプラズマ輸送の制御におけるZFの重要な役割を明らかにしている。
