Kinetic magnetic dynamo in a sheath-limited high-temperature and low-density plasma

X Z Tang2011年Plasma Physics and Controlled FusionIF 2.2出版社

In a sheath-limited high-temperature and low-density plasma, energy and particle loss to an absorbing wall can set up a temperature anisotropy in which the normal-to-the-wall temperature is significantly lower than that of the parallel-to-the-wall directions, even for an upstream plasma source with isotropic temperature. This temperature anisotropy excites the Weibel instability and introduces a self-generated magnetic field which is parallel to the wall surface. The self-generated magnetic field modifies the sheath/presheath plasma in two ways upon saturation: (1) it suppresses the net energy loss rate to the absorbing wall, primarily through the ion channel and (2) it transfers energy between different degrees of freedom and reduces the plasma temperature anisotropy.

シース制限された高温・低密度プラズマにおいて、吸収壁へのエネルギーおよび粒子の損失は、壁に垂直な方向の温度が壁に平行な方向の温度よりも有意に低くなる温度異方性を生じ得る。これは、上流のプラズマ源が等方的な温度分布を持つ場合であっても同様である。この温度異方性はワイベル不安定性を励起し、壁面に平行な自己生成磁場を誘起する。この自己生成磁場は、飽和に達すると以下の2つの方法でシース/プレシースプラズマを変調する:(1) 主にイオンチャネルを通じて吸収壁への正味のエネルギー損失率を抑制する、(2) 異なる自由度間でエネルギーを移動させ、プラズマの温度異方性を低減する。
