本文深入研究了平面真空二极管的无碰撞动理学理论,探究脉冲周期(ectonic)阴极等离子体发射机制如何影响阴极等离子体的非热膨胀及“异常”离子加速;同时还探究了脉冲周期发射如何影响阴极材料产生的多电荷离子的相对运动动力学。通过动理学理论分析得出,ectonic发射机制既影响等离子体膨胀的宏观图景,也影响一个完整发射周期内电势重新分布的复杂过程。

英文摘要

In this paper, the authors delve into the collisionless kinetic theory of planar vacuum diodes to investigate how a pulse-periodic (ectonic) cathode plasma emission mechanism influences the non-thermal expansion of the cathode plasma and "anomalous" ion acceleration. Another aspect explored in this paper is how pulse-periodic emission affects the comparative dynamics of motion of multi-charged ions from the cathode material. Using kinetic theory, we conclude that the ectonic emission mechanism affects both the macroscopic picture of plasma expansion and the intricacies of electric potential redistribution over one complete emission period.
