Topology of steady-state plasma configurations in transverse self-consistent fields: Spatial-periodic plasma structures: I

N.N. Komarov1963年被引用 7Nuclear FusionIF 3出版社

Neglecting collisions, we consider a kinetic approximation for the Boltzmann function of particle distribution with a longitudinal macroscopic velocity that does not depend on the coordinates. With it we solve the two-dimensional problem (∂/∂x≠0, ∂/∂y≠0, ∂/∂z=0) of the equilibrium configurations of an l-component plasma in self-consistent internal and external transverse magnetic fields (and also in electric fields caused by a non-compensation of plasma charge as a whole).The solution obtained with the given assumptions is a general one and permits one to make a broad analysis of equilibrium plasma configurations with longitudinal currents in self-consistent external and internal transverse fields. It is shown that existence of steady plasma states with a spatial-periodic structure is possible. This corresponds to the data of experiments in which it has been reliably established that a plasma arising in pinch discharges has a fibrous structure characterized by a definite space periodicity.

衝突を無視して、座標に依存しない縦方向の巨視的速度を伴う粒子分布のボルツマン関数に対する運動論的近似を考察する。これを用いて、自己無撞着な内部および外部の横磁場中(また、プラズマ全体の電荷の非補償によって生じる電場中)でのl成分プラズマの平衡配位の二次元問題(∂/∂x≠0, ∂/∂y≠0, ∂/∂z=0)を解く。与えられた仮定の下で得られる解は一般的なものであり、自己無撞着な外部および内部の横場中での縦電流を伴う平衡配位の広範な解析を可能にする。空間周期構造を持つ定常プラズマ状態の存在が可能であることが示される。これは、ピンチ放電において生じるプラズマが、明確な空間周期性によって特徴づけられる繊維状構造を持つことが確実に確立されている実験データに対応する。
