Transverse oscillating field current drive in spherical plasmas

D Brotherton-Ratcliffe, R G Storer1989年Plasma Physics and Controlled FusionIF 2.2出版社

The technique of driving steady Hall currents in plasmas using a transverse oscillating magnetic field is studied numerically under the approximation of negligible ion flow. The authors model a uniformly dense and resistive spherical plasma bounded by an insulating wall and immersed in a uniform magnetic field which has both an oscillating component (of frequency Omega ) and an orthogonal constant 'vertical' component. The authors formulate the (3-D time-dependent) problem in terms of a spatial expansion in vector spherical harmonics and a temporal expansion in Fourier harmonics.

横断振動磁場を用いてプラズマ中のホール電流を駆動する手法を、イオン流が無視できる近似の下で数値的に研究する。著者らは、一様密度で抵抗性の球状プラズマが、絶縁性の壁に囲まれ、振動成分(周波数Ω)と直交する定常「鉛直」成分の両方を有する一様磁場中に置かれた系をモデル化する。著者らは、(3次元の)時間依存問題を、ベクトル球面調和関数による空間展開とフーリエ調和関数による時間展開を用いて定式化する。
