Formation of solid helical filaments at temperatures of superfluid helium as self-organization phenomena in ultracold dusty plasma

摘要

е, levitating in the gas discharge at the temperature ~2?K and pressure 4?Pa have been observed for the first time. Analysis of the experimental conditions and the filament composition allows us to conclude that the filaments and nanoclusters were formed due to ion sputtering of dielectric material during the experiments.
