Abstract
Two novel types of instabilities in inhomogeneous, dusty plasma are conside red. It is shown that spatial dust charge variation provides an effective m echanism to excite the motion of particles. The results of experimental obs ervation of various self-excited motions of dust particles in a dc-discharg e plasma are presented. Conditions suitable for growing the considered inst abilities in the dc-glow discharge are discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
