Spontaneous and driven reduced turbulence modes in the RFX reversed field pinch

S Martini, D Terranova, P Innocente, T Bolzonella1999年Plasma Physics and Controlled FusionIF 2.2出版社

The reversed field pinch (RFP) is a highly-sheared nearly force-free magnetic field configuration, which is almost entirely self-generated, via a dynamo process. A still open question is the level of turbulence entailed by the dynamo and how it could be mitigated in order to improve plasma confinement. The paper addresses the issue, first discussing the properties of the magnetic profiles of RFX in relation to other RFPs, then analysing some transient enhanced confinement modes which suggest that the improved confinement is due to a reduced dynamo action.

反転磁場ピンチ(RFP)は、ほぼ完全に自己生成される、高いシアを有するほぼ力のない磁場配位であり、ダイナモ過程を介して生成される。依然として未解決の問題は、ダイナモに伴う乱流のレベルと、プラズマ閉じ込めを改善するためにそれをどのように緩和できるかである。本論文はこの問題を取り上げ、まず他のRFPとの関連におけるRFPの磁場プロファイルの特性について論じ、次に、改善された閉じ込めがダイナモ作用の低減によるものであることを示すいくつかの過渡的な改善閉じ込めモードを分析する。
