Recombination instability of dust plasma of a non-self-sustained discharge in the collision regime

Recombination instability of a dust plasma of a non-self-sustained discharge maintained by an ionizing radiation beam has been studied for the conditions when the collisions of ions with atoms in the charged layer of a dust particle considerably affect the ion current to the particle. It has been shown that the collisions of ions elevate the stability of the plasma. The dependence of the conditions for the evolution of instability and its increment on the discharge parameters has been analyzed.
