Angular distribution of current to a sphere in a flowing, weakly magnetized plasma with negligible Debye length

Leonardo Patacchini, Ian H Hutchinson2007年Plasma Physics and Controlled FusionIF 2.2出版社

The influence of a weak magnetic field (B) on the ion current collected by a spherical electrode is studied by means of the 2v-3d particle in cell code SCEPTIC in the limit of zero Debye length. The ion current dependence on B for low fields, shown to be linear, is compared with analytic expressions valid in the magnetized free-flight limit. In the flow-free regime, expressions for the angular distribution of current at different ion temperatures are provided. The configuration in which the plasma is drifting in the B-direction is investigated as well, and a Mach-probe calibration valid for equal temperature ions and electrons is given.

弱磁場(B)が球形電極によって収集されるイオン電流に及ぼす影響を、デバイ長ゼロの極限において、2v-3d粒子インセルコードSCEPTICを用いて研究した。低磁場におけるイオン電流のB依存性は線形であることが示され、磁化された自由飛行極限において有効な解析式と比較された。無流動領域では、異なるイオン温度における電流の角度分布の式が提供される。さらに、プラズマがB方向にドリフトする配置についても調査され、電子とイオンの温度が等しい場合に有効なマッハプローブ較正が与えられる。
