Abstract of the Disclosure An improved anode-system for producing uniform gradient coatings by magnetic sputtering is disclosed, comprising a pair of anode plates asymmetrically designed and positioned along the length of the cathode. The magnetic flux lines form a tunnel in a closed loop on the sputtering surface. The glow discharge is confined by the magnetic field to the region adjacent the sputtering surface.
