Magnetic well depth in EBT and sensitivity to hot-electron ring geometry

E.F. Jaeger, L.A. Berry, C.L. Hedrick, R.K. Richards1985年被引用 8Nuclear FusionIF 3出版社

The paper examines the possibility that diamagnetic currents in the hot-electron rings in the ELMO Bumpy Torus (EBT) plasma are strong enough to reverse gradients in ∮ dℓ/B, thereby providing gross magnetohydrodynamic stability. Using a two-dimensional solution to the Grad-Shafranov equation with tensor pressure, the electromotive force induced in a diamagnetic loop surrounding the EBT plasma is computed. This allows a direct comparison between the calculated and measured diamagnetic loop signals for different values of perpendicular energy stored in the electron rings.

本論文は、ELMOバンピートーラス(EBT)プラズマ中の高温電子リングにおける反磁性電流が、∮dℓ/Bの勾配を反転させるのに十分な強さを持ち、それによって巨視的磁気流体力学安定性をもたらす可能性を検討するものである。テンソル圧力を伴うGrad-Shafranov方程式の二次元解を用いて、EBTプラズマを取り囲む反磁性ループに誘起される起電力を計算する。これにより、電子リングに蓄えられた垂直エネルギーが異なる値に対して、計算された反磁性ループ信号と測定された反磁性ループ信号の直接比較が可能となる。
