A model for the turbulence in the scrape-off layer of tokamaks

The fluid theory of electrostatic perturbations in a scrape-off layer (SOL) plasma is analysed. The main difficulty is that the edge is theoretically found to be stable, while experimentally it is unstable. A possible explanation relies on the fact that the commonly used ballooning representation is not correct in the SOL. An alternative representation is proposed which reproduces the instability of the edge in several simple configurations and explains many experimental features.

スクレイプオフ層(SOL)における静電擾乱の流体理論を解析する。主な困難は、エッジが理論的には安定であると見出される一方で、実験的には不安定であることである。有力な説明の一つは、一般的に用いられるバルーニング表現がSOLにおいては正しくないという事実に依拠している。いくつかの単純な配位におけるエッジの不安定性を再現し、多くの実験的特徴を説明する代替表現を提案する。
