A perturbation theory of transverse oscillating field current drive in spherical plasmas

D Brotherton-Ratcliffe, S Xu1989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 analytically under the approximation of negligible ion flow and in the weakly non-linear limit. The authors consider the situation of a uniform (transverse) oscillating field and a uniform vertical field applied to a spherical uniformly dense and resistive plasma with spherical insulating wall. They model the oscillating field as two counter-rotating fields; a transformation which allows the deduction of many of the properties of this form of current drive from the existing theory of current drive by rotating magnetic fields.

横断振動磁場を用いてプラズマ中の定常ホール電流を駆動する手法について、イオン流を無視できる近似と弱非線形極限の下で解析的に研究する。著者らは、球状の一様密度プラズマ(抵抗性を有し、球状の絶縁壁で囲まれる)に、一様な横断振動磁場と一様な垂直磁場が印加された状況を考察する。振動磁場を二つの逆回転磁場としてモデル化する。この変換により、この形式の電流駆動の多くの特性を、回転磁場による電流駆動の既存理論から導出することが可能となる。
