Research output: Contribution to journalConference articlepeer-review


In this work the kinetics of macroparticle charging in the rarified part of the arc plasma jet are studeid. The sheath in the vicinity of the macroparticle is collissionless and the problem with different Debye length to macroparticle radius ratio is analysed. Maxwellian velocity distribution functions with different temperatures for the electrons and ions in an arbitrary ratio are allowed in the model. The influence of the plasma drift velocity on the macroparticle charging is discussed.
