增强束等离子体作用下表面腐蚀斑的微观结构
Microstructure of erosion spots on the surface interacting with filamented beam plasma
摘要：
本文分析了在马瑟型等离子体聚焦器中观察到的直径为10-100微米的同轴环内的微米级腐蚀斑的精细结构。拓扑结构的相似性，这种结构的电流丝，观察到的Filippov型等离子体焦点和直Z-箍缩，示出。解释这种结构的可能性，在以前提出的假设，长寿命的电流灯丝的形成，由于在放电中的纳米粉尘的电动聚集，进行了讨论。
英文摘要：
The fine structure of micron-sized erosion spots within coaxial rings of 10-100 micron diameter, observed in the Mather type plasma focus, is analyzed. The topological similarity of this structuring to that of electric current filaments, observed in the Filippov type plasma foci and straight Z-pinches, is shown. The possibility of interpreting this structuring in terms of the formerly suggested hypothesis for long-lived electric current filament formation, due to electrodynamic aggregation of nanodust in electric discharges, is discussed.
