Particle simulation study of dust particle dynamics in sheaths

Smirnov, R.*; Tomita, Yukihiro*; Takizuka, Tomonori; Takayama, Arimichi*; Chutov, Y.*

Dynamics of dust particles in a divertor plasma is simulated using numerical solutions of dust momentum and charging equations. Spatial distributions of plasma parameters in a divertor are obtained with particle simulations including electron-impact ionization. We find that the large-radius dust particles are not released from the divertor plate. The middle-size-radius particles are released but retuned to the plate. The small-radius particles can be released from the plate.
