Vacuum arc plasma jets and their applications

Summary form only given, as follows. In this work state-of-art of the vacuum arc plasma jet simulation will be reviewed The principles of applications will be also discussed. Several mechanisms of macroparticle elimination based on the fact that macroparticles are charged in the plasma will be considered. The vacuum arc plasma jet flow will be analyzed using the 2D hydrodynamic free plasma jet boundary expansion model. Several effects will be considered in this context, such as multiply charged ion transport and separation, plasma jet behavior in a magnetic field and effects associated with electrode geometry. The diffuse vacuum arc in a magnetic field and V-shape arc voltage characteristics in a magnetic field will be discussed.
