Microstructure of erosion spots on the surface interacting with filamented beam plasma
Abstract
Description
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.
