The purpose of the work is to determine the main physical mechanisms that can affect the state of micro-inclusions in a dense dusty plasma during its passage through plasma-dynamic systems with fast electrons. The goal of the work is an in-depth theoretical study of the influence of geometric and electrophysical parameters of plasmodynamic systems with fast electrons on flows of low-energy dusty plasma and experimental verification of the conclusions of numerical and analytical calculations. Research methods - the application of advanced and traditional electrophysical methods of studying plasma flows in plasma dynamic systems, determination of the limit possibilities of the efficiency of plasma flow cleaning by analytical methods of mathematical physics and the involvement of numerical methods for modeling the temperature dynamics of the micro-droplet fraction in plasma flows. Experimental studies of the dynamics of the electrophysical characteristics of a discharge plasma with a hollow cathode were carried out using two types of pulse-periodic high-voltage power sources of voltage and current. It is shown that the use of pulsed current sources provides significantly more stable discharge burning in the working range of argon pressure changes (2.5 – 10*10-4 Torr). At the same time, the temperature of plasma electrons of a discharge with power from a voltage source is higher and reaches 65 eV. Product Description popup.authors Bazhenov Volodymyr Yu.
