Abstract
The ionized unmagnetized dusty plasma are investigated. This plasma is penetrated by an energized electron beam and is composed of Maxwellian electrons, ions and positively charged dust grains. The multifluid equations are scaled using the characteristic time and length for elastic collisions between and neutral atoms and the Poisson equation relates the plasma potential fluctuations with charged particle densities. The deduced dimensionless dispersion relation results scaled in terms of the dust acoustic (DA) and dust ion acoustic (IA) wave speeds and different limits are examined in relation with the plasma properties. Contrary to dust free plasmas (Refs. 5,6) the unstable modes are found even in the absence of the ionizing electron beam and the the role of the injected current density is also discussed. 1. P. K.
