Energy confinement in the T-10 Tokamak and canonic profile models

Yu N Dnestrovskii, G V Pereverzev1988年Plasma Physics and Controlled FusionIF 2.2出版社

A classification of experimental results on electron cyclotron resonance heating (ECRH) in the T-10 tokamak is presented. Analysis of the experiments is consistent with two energy balance models. The first is based on the idea of profile consistency of the plasma current and pressure. The on-axis and off-axis ECRH as well as the heat wave propagation in T-10 can be reasonably represented in this way. In addition, this model allows the L to H mode transition to be described as the bifurcation of the solutions of a set of non-linear equations. The second model is based on the idea of a thermal pinch produced by a toroidal electric field. The electron temperature profiles under ohmic heating as well as under ECRH can be described by this model. Furthermore, this approach explains the cause of the confinement degradation under non-ohmic plasma heating (L-mode).

T-10トカマクにおける電子サイクロトロン共鳴加熱(ECRH)の実験結果の分類を提示する。実験の解析は、2つのエネルギー平衡モデルと整合する。最初のモデルは、プラズマ電流と圧力のプロファイル整合性の考えに基づく。軸上および軸外ECRH、ならびにT-10における熱波伝播は、この方法で合理的に表現できる。さらに、このモデルは、LモードからHモードへの遷移を、一連の非線形方程式の解の分岐として記述することを可能にする。2番目のモデルは、トロイダル電場によって生成される熱ピンチの考えに基づく。オーム加熱下およびECRH下の電子温度分布は、このモデルによって記述できる。さらに、このアプローチは、非オームプラズマ加熱(Lモード)における閉じ込め劣化の原因を説明する。
