Single helical axis configurations are emerging as the natural state for high-current reversed field pinch plasmas. These states feature the presence of transport barriers in the core plasma. Here we present a method for computing the equilibrium magnetic surfaces for these states in the force-free approximation, which has been implemented in the SHEq code. The method is based on the superposition of a zeroth-order axisymmetric equilibrium and of a first-order helical perturbation computed according to Newcomb's equation supplemented with edge magnetic field measurements. The mapping of the measured electron temperature profiles, soft x-ray emission and interferometric density measurements on the computed magnetic surfaces demonstrates the quality of the equilibrium reconstruction. The procedure for computing flux surface averages is illustrated, and applied to the evaluation of the thermal conductivity profile. The consistency of the evaluated equilibria with Ohm's law is also discussed.

単一ヘリカル軸配位は、高電流逆転磁場ピンチプラズマの自然な状態として現れつつある。これらの状態は、コアプラズマにおける輸送障壁の存在を特徴とする。ここでは、SHEqコードに実装された、力学的自由近似におけるこれらの状態の平衡磁気面を計算する方法を提示する。この方法は、ゼロ次軸対称平衡と、エッジ磁場測定を補足したNewcomb方程式に従って計算される一次ヘリカル摂動の重ね合わせに基づく。測定された電子温度分布、軟X線放射、および干渉計による密度測定のマッピングは、平衡再構成の品質を示している。磁束面平均を計算する手順を説明し、熱伝導率分布の評価に適用する。評価された平衡のオームの法則との整合性についても議論する。
