Z pinch equilibria maintained by means of n=0 r.f. fields

W N Hugrass1992年Plasma Physics and Controlled FusionIF 2.2出版社

The use of n=0 radio frequency (r.f.), fields to maintain linear Z pinch equilibria is investigated numerically in the MHD approximation. Self-consistent equilibria are computed assuming uniform temperature. The externally applied fields do not excite any waves in the plasma other than the resistive mode because the RF current density is parallel to the equilibrium magnetic field. The equilibrium current profiles are hollow as expected and the electron density is nearly uniform, in the central region. Potential applications for this configuration both in plasma processing and in fusion are discussed.

n=0の高周波(r.f.)場を用いて線形Zピンチ平衡を維持することを、MHD近似の下で数値的に調べた。自己無撞着な平衡は、一様な温度を仮定して計算される。外部から印加された場は、RF電流密度が平衡磁場に平行であるため、抵抗性モード以外のプラズマ中の波動を励起しない。平衡電流分布は予想通り中空状であり、電子密度は中心領域でほぼ一様である。この配位のプラズマプロセッシングおよび核融合における応用の可能性について議論する。
