Dust structures in cryogenic dc discharge: Some suggestions for future research
Abstract
In this work, the cryogenic dusty plasma, which is represented by a mixture of two dust components with different structural and dynamical properties, was experimentally investigated. Experiments were conducted in dc glow discharge at temperatures 10 and 77 K using CeO2 micron powder as a dust. In dust structures obtained one of the components consists of dust particles with chain-like ordering (dust chains) and another component consists of fast- moving particles orbiting horizontally through the first component (“crazy” particles). Dust particle velocity distribution functions were obtained. The possible reasons of two-component dust structure formation were discussed.
