Experimental Investigation of the Properties of Plasma-Dust Formations on Pulsed Plasma Accelerator

In this paper, we present the results of experimental investigation of the properties of dusty plasma formed in a pulsed plasma accelerator (IPU-30) through the interaction of pulsed plasma beams with a carbon-based target. In the experiments, the interaction of beams of the pulsed plasma with the surface of the carbon plates affords instantaneous heating of the target substrate and subsequent ejection of dust particles from the surface of the plates into the plasma bulk. These dust particles are dragged by the plasma beam creating a moving plasma-dust cloud. A high-speed camera (Phantom VEO710S) is used to obtain the velocity of the dust particles in a beam of the pulsed plasma. Ejection of dust particles is investigated at two different values of the discharge voltage (7 and 12 kV).
