Travelling wave current drive

J A Staines, R G Storer1991年Plasma Physics and Controlled FusionIF 2.2出版社

A computational study is undertaken of traveling wave current drive based on the nonlinear interaction between radio-frequency components of the current and magnetic field induced in a plasma. Results are presented which describe the current drive in the Synchromak (m=0), double helix (m=1) and, in particular, the computationally more complex helical mesh (m=+1 and m=-1) experiments. A general technique for the numerical solution for the driven currents is developed which includes Fourier harmonics to arbitrary order for this variety of external coil structures. By adjusting the relative currents in the helical mesh external coils, considerable flexibility in the control of both poloidal and toroidal current drive results.

進行波電流駆動の計算機研究が、プラズマ中に誘起された電流の高周波成分と磁場との間の非線形相互作用に基づいて行われた。シンクロマック(m=0)、二重螺旋(m=1)、そして特に計算上より複雑な螺旋メッシュ(m=+1およびm=-1)実験における電流駆動を記述する結果が提示される。駆動電流の数値解法のための一般的な手法が開発され、これはこの種の外部コイル構造に対して任意次数のフーリエ高調波を含むものである。螺旋メッシュ外部コイルにおける相対電流を調整することにより、ポロイダルおよびトロイダル電流駆動の両方の制御においてかなりの柔軟性が得られる結果となる。
