Magnetic reconnection rate during sawtooth crashes in ASDEX Upgrade

The radial velocity of the plasma core during the sawtooth crashes has been measured for the first time with electron cyclotron emission imaging diagnostic. The measurements have been compared with nonlinear two-fluid simulation. The comparison reveals good qualitative and quantitative agreement, which indicates that two-fluid effects (inertia and pressure gradient of electrons) are sufficient for the correct prediction of the experimental results. Contrarily, the crash time of the Kadomtsev model, which is based on a single-fluid picture of magnetic reconnection, disagrees with the experimental results.

プラズマコアのクラッシュ(鋸歯状振動)中の径方向速度が、電子サイクロトロン放射イメージング診断により初めて測定された。この測定結果は、非線形二流体シミュレーションと比較された。その比較により、定性的・定量的に良好な一致が示され、二流体効果(慣性および圧力勾配)が実験結果を正確に予測するために十分であることが明らかになった。対照的に、磁気リコネクションの一流体描像に基づくカドムツェフモデルによるクラッシュ時間は、実験結果と一致しなかった。
