Relaxed, minimum dissipation states, for a flux core spheromak sustained by helicity injection

Ricardo Farengo, K I Caputi2002年Plasma Physics and Controlled FusionIF 2.2出版社

Minimum dissipation states of a flux core spheromak sustained by helicity injection are presented. Helicity balance is used as a constraint and the resistivity is considered to be non-uniform. Two types of relaxed states are found: one has a central core formed by the flux that links the electrodes surrounded by a toroidal region of closed flux surfaces and the other has the open flux wrapped around the closed flux surfaces. The analysis includes two important features: a self-consistent calculation of the magnetic flux through the electrodes and a resistivity which depends upon the poloidal flux. Non-uniform resistivity effects can be very important because of the qualitative and quantitative changes they produce in the safety factor profile.

ヘリシティ注入によって維持されるフラックスコア・スフェロマックの最小散逸状態について提示する。ヘリシティバランスを拘束条件として用い、抵抗率は非一様であると考える。2種類の緩和状態が見出される:1つは電極を結ぶ磁束によって形成される中心コアを持ち、その周囲を閉じた磁束面のトロイダル領域が取り囲むものであり、もう1つは閉じた磁束面の周囲に開いた磁束が巻き付く構造を持つものである。この解析には2つの重要な特徴が含まれる:電極を通る磁束の自己無撞着な計算と、ポロイダル磁束に依存する抵抗率である。非一様抵抗率の効果は、安全係数プロファイルにもたらす定性的および定量的な変化のために、非常に重要となり得る。
