Basic loss processes in thermally ionized magnetoplasmas: Part I, Theory

A theoretical explanation for the experimentally observed enhanced surface recombination of the ions in a thermally ionized magnetoplasma in a Q-device is proposed. It is based on a collisionless treatment which yields a non-Maxwellian velocity distribution for the plasma particles (section 2). In section 3 the influence of rate collisions on the velocity distribution , particularly in double-ended operation, (D.E., bothendplates hot) is discussed and it is shown that even in the case of a partially thermalized plasma with a thermalization rat e of about 50% the surface recombination causes still a J0 ∼ n dependence instead of a J0 ∼ n2 dependence as found in the case of a fully thermalized plasma.

熱電離磁化プラズマ中のイオンの表面再結合が実験的に観測された増強を示すことに対する理論的説明が提案される。これは、プラズマ粒子の非マクスウェル速度分布をもたらす無衝突的取り扱いに基づく(第2節)。第3節では、特に両端動作(D.E.、両端板加熱)における速度分布に対する衝突率の影響が議論され、約50%の熱化率を持つ部分的に熱化されたプラズマの場合でも、表面再結合が依然としてJ0 ∼ n依存性をもたらすことが示される。一方、完全に熱化されたプラズマの場合に見られるJ0 ∼ n2依存性とは対照的である。
