Rapid Rotation of a Dust Structure in the Region of Narrowing of a Glow Discharge Current Channel in a Magnetic Field of ~1 T
摘要
Abstract
The mechanisms of rotation of dust particles in a magnetic field inside an insert that determines the position of the first standing stratum in a glow discharge are considered. It has been shown that in fields exceeding 0.5 T, the drag of dust particles by a neutral gas can acquire considerable significance in addition to ion drag. Taking this mechanism into account leads to a significant increase in the rotation rate and good agreement with experimental data.
