A Poynting's Theorem method is used for evaluating the volt-second consumption in a tokamak discharge. The method accurately identifies the inductive and resistive components of the volt-second consumption, and allows both quantities to be determined from magnetic measurements made outside the plasma. Only simple computational techniques are required. Application of the method to typical Doublet III near-circular plasmas (R = 1.43 m, a = 0.44 m, b/a ≅ 1.2) indicates that the flux at the plasma surface required to establish the current flat-top is 2.0 ± 0.2 V·s/MA. Approximately 40% of this flux is consumed in resistive dissipation. This division between resistive and inductive flux differs significantly from that obtained using an alternative data analysis method in which the resistive loss is evaluated at the plasma axis. The reasons for the difference are discussed.

ポインティングの定理法は、トカマク放電におけるボルト秒消費の評価に用いられる。この方法は、ボルト秒消費の誘導成分と抵抗成分を正確に識別し、両方の量をプラズマ外部で行われた磁気測定から決定することを可能にする。単純な計算手法のみが必要とされる。典型的なDoublet IIIのほぼ円形プラズマ(R = 1.43 m、a = 0.44 m、b/a ≅ 1.2)への本法の適用は、電流フラットトップを確立するためにプラズマ表面で必要とされるフラックスが2.0 ± 0.2 V·s/MAであることを示している。このフラックスの約40%が抵抗散逸で消費される。抵抗フラックスと誘導フラックスの間のこの分割は、抵抗損失がプラズマ軸上で評価される代替データ解析法を用いて得られたものとは有意に異なる。この差異の理由について議論する。
