Dust acoustic waves in a dc glow-discharge plasma

Journal of Experimental and Theoretical Physics volume 89, pages 477–480 (1999)Cite this article

Abstract

The spontaneous excitation of low-frequency oscillations of the macroparticle density in ordered dust structures levitating in standing striations of a dc glow discharge is discovered. It is concluded on the basis of a simplified linear model of an ideal collisionless plasma that the observed instability is caused by the drift motion of ions relative to the dust, which leads to the excitation of dust acoustic oscillations of the plasma.
