A kinetic trajectory simulation model for magnetized plasma sheath

R Chalise, R Khanal2012年Plasma Physics and Controlled FusionIF 2.2出版社

The plasma-sheath region in an oblique magnetic field has been studied using a kinetic trajectory simulation model. It has been observed that the magnetized plasma-sheath region has two distinct regions: magnetic field dominant region lying close to the sheath entrance and electric field dominant region (almost no effect of magnetic field) lying close to the wall. The particle densities and potential decrease as we move towards the wall, which becomes prominent as the strength and obliqueness of the magnetic field increase. Our results agree well with previous works from other models and hence, we expect our model to provide a basis for studying all types of magnetized plasmas, using the kinetic approach.

斜め磁場中のプラズマ・シース領域が、運動論的軌道シミュレーションモデルを用いて研究されてきた。磁化されたプラズマ・シース領域には2つの異なる領域があることが観測されている:シース入口の近くに位置する磁場支配領域と、粒子の近くに位置する電場支配領域(磁場の影響がほとんどない)である。粒子密度と電位は、壁に向かって移動するにつれて減少し、これは磁場の強さと斜度が増すにつれて顕著になる。我々の結果は、他のモデルによる先行研究とよく一致しており、したがって、我々のモデルが運動論的アプローチを用いてあらゆる種類の磁化プラズマを研究するための基礎を提供することを期待している。
