Stationary magnetic entropy tokamak states and experimental observations

E. Minardi, C. Sozzi, P. Mantica, JET-EFDA contributors2008年被引用 1Nuclear FusionIF 3出版社

The assumption that the tokamak magnetic configuration at equilibrium is associated with the stationary magnetic entropy and with minimum plasma thermal energy leads to the prediction of definite profiles for the induced current density and for the pressure. These profiles should characterize the states spontaneously assumed by the tokamak under normal conditions (to be defined in the text).The theoretical results are compared with the observations collected from different tokamaks, plasma regimes and heating methods, taking into account the possible existence of non-inductive currents. The comparison allows the identification of the limits of validity of the model and confirms the robustness, within these limits, of the magnetic entropy concept for the description of the 'privileged' tokamak states.

日本語訳

トカマク磁気配位が平衡状態において定常磁気エントロピーとプラズマ熱エネルギーの最小化と関連付けられるという仮定は、誘導電流密度と圧力の明確な分布を予測するものである。これらの分布は、通常の条件下(本文中で定義される)でトカマクが自発的に取る状態を特徴づけるはずである。理論的結果は、異なるトカマク、プラズマ領域、加熱方法から収集された観測データと比較され、非誘導電流の存在可能性が考慮される。この比較により、モデルの適用限界が特定され、これらの限界内において、磁気エントロピー概念が「特権的な」トカマク状態の記述に対して頑健性を持つことが確認される。
