Resonance between passing fast ions and MHD instabilities both in the tokamak and the RFP configurations

M. Gobbin, R.B. White, L. Marrelli, P. Martin2008年被引用 21Nuclear FusionIF 3出版社

Suprathermal ions in fusion plasmas have different confinement properties in tokamak and reversed field pinch (RFP) configurations. These differences are explained in terms of guiding centre drifts by an analytical approach. Magnetic field perturbations and passing fast ions can satisfy resonance conditions which do not hold for thermal or low energy particles. Such a resonance is controlled by a generalization for passing fast ions of the safety factor parameter. Applications to experimental situations show good agreement in predicting the radial position of the resonances in the fast ion phase space. Numerical simulations in RFP devices are qualitatively consistent with the longer confinement times of fast ions, especially in helical regimes.

核融合プラズマ中の超熱イオンは、トカマク配位と逆転磁場ピンチ(RFP)配位において異なる閉じ込め特性を持つ。これらの差異は、解析的アプローチによって案内中心ドリフトの観点から説明される。磁場摂動と通過高速イオンは、熱的または低エネルギー粒子には成り立たない共鳴条件を満たすことができる。そのような共鳴は、安全係数パラメータの通過高速イオンへの一般化によって制御される。実験状況への適用は、高速イオン位相空間における共鳴の半径方向位置の予測において良い一致を示す。RFP装置における数値シミュレーションは、特にヘリカル状態における高速イオンのより長い閉じ込め時間と定性的に一致する。
