Abstract :
In filtered vacuum arc deposition, the plasma produced by spots is passed through a curved duct by means of a magnetic field, in order to remove macroparticles which would otherwise contaminate the deposition. In this paper, it is suggested that the plasma throughput efficiency in such a magnetic filter may be enhanced by locating the plasma source (e.g. the vacuum arc cathode) in the free-passage zone at the duct entrance
