The temporal-spatial structures of plasma flows and turbulence around tearing mode islands are presented. The experiments were performed using Langmuir probe arrays in the edge plasmas of J-TEXT tokamak. The correlation analyses clearly show that the flows have similar structures of m/n  =  3/1 as the magnetic island does (m and n are the poloidal and toroidal mode numbers, respectively). The sign of the potential fluctuations for the flows inverses and the powers significantly reduce at q  =  3 surface. Approaching to the last closed flux surface for the magnetic islands, the radially elongated flow structure forms. The flows are concentrated near separatrix and show quadrupole structures. The turbulence is concentrated near X-point and partly trapped inside the magnetic islands.

テアリングモード磁気島周辺におけるプラズマ流と乱流の時空間構造を提示する。実験はJ-TEXTトカマクの周辺プラズマにおいてラングミュアプローブアレイを用いて実施された。相関解析により、プラズマ流が磁気島と同様のm/n = 3/1の構造を有することが明確に示された(mおよびnはそれぞれポロイダルモード数およびトロイダルモード数である)。q = 3磁気面において、ポテンシャル変動の符号が反転し、パワーが著しく減少する。磁気島に対する最終閉磁気面に近づくにつれて、径方向に伸長した流れ構造が形成される。プラズマ流はセパラトリクス近傍に集中し、四重極構造を示す。乱流はX点近傍に集中し、磁気島内部に部分的に捕捉される。
