Abstract
Description
St=λd[qeVTe]3/4 ・・・(1)
プラズマシースは、電荷を有する(通常は正電荷)薄層であり、プラズマに対して露出した任意の面を囲む。プラズマシースは通常、電子とイオンの運動性の違いに起因して生じる。プラズマに対して露出した面は通常、比較的重いイオンに比べて「軽い」初期電子束に起因して、負電荷にチャージされる。その結果、正種がその面に取り付き、負電荷が除去され、厚い正電荷層またはシースを形成する。シースはプラズマと接する面の影響を遮断し、シース層の厚さは上記式(1)が記載するパラメータに依拠する。プラズマシース(およびプリシース)において、電子とイオンが衝突し、一方で中性種は容易にシースを移動できる。シースを通過して移動する際に、中性種はイオン化される場合がある。
