Characterization of a quarter torus filter for vacuum arc ion flux transmission
Measurements on the ion flux transmission in a magnetically filtered d-c vacuum arc are presented. The device includes a metallic plasma-generating chamber with water-cooled electrodes coupled to a substrate chamber through a quarter-torus magnetic filter. It is employed a Copper cathode (6 cm in di...

The filter consists in a steel cylinder 500 mm length and 100 mm inner diameter with 90° of bending angle and corrugated lateral walls, surrounded by a magnetic field generating coil. The arc is operated at a current level of 100 A, and the intensity of the filtering magnetic field was in the range 0-200 G (measured at the knee of the filter).
