Creation of stable dust structures in the glow discharge in magnetic fields of up to 15000 G

The dusty plasma created in the dust trap in strata of the glow discharge in the strong magnetic field was studied. The conditions were found that make it possible to avoid the development of instabilities in the glow discharge plasma in the magnetic field. For the first time, in the magnetic field...

Summary:The dusty plasma created in the dust trap in strata of the glow discharge in the strong magnetic field was studied. The conditions were found that make it possible to avoid the development of instabilities in the glow discharge plasma in the magnetic field. For the first time, in the magnetic field range of higher than 10000 G, the dust structures were obtained. The rotational speed as a function of the magnetic field induction was studied. The experimental conditions were discussed under which the stable dust structures can be created.
