Nuclear Induced Dusty Plasma Structures

DOI: 10.1016/b978-044450398-5/50084-1


Publisher Summary This chapter describes the experiments conducted in the nuclear-induced plasma with micron-sized dust macro-particles injected into it. The experiments suggest that the plasma was formed in the atmospheric air by alpha-particles and fission fragments of 252Cf as well as by beta-active particles. In both cases, ordered liquid-type structures of dust particles levitating in the interelectrode space were observed. When the electric field intensity was less than 20 V/cm, regions of levitation of macro-particles forming ordered liquid-type dust structures were observed in the interelectrode space. With an increase in the electric field, the vortex movement of macro-particles occurred. The initial direction of a rotation of dust particles was from the radioactive source.
