Positively Charged Microparticles in Plasma

Abstract

The processes of recharging and changing the temperature of a positively charged microparticle (MP) introduced into plasma are considered. It is assumed that the MP is charged to a positive charge outside the plasma, and then enters the plasma due to the accelerating field. For various values of plasma density and temperature, a numerical solution of the energy and current balance equations of a MP is obtained. The equation that determines the evaporation of particles is solved numerically. The time dependence of the radius of a MP during evaporation has been obtained.
