Abstract
Abstract Cathode arc discharge evaporating device having a body of revolution as cathode. The target surface is arranged at the outside surface of the body of revolution. To control movement of the arc spot a magnetic field generating device is provided inside the body of revolution, which may be moveable with respect to the cathode.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
74 words
Cathode arc evaporating device, comprising an evaporation surface of the material to be evaporated formed as a surface of a hollow body of revolution, means for supporting said evaporation surface for rotation about an axis, and at least one arc spot steering magnetic field generating device supported within said evaporation surface for movement in a direction parallel to the axis of rotation of said evaporation surface for avoiding non-uniform erosion of said evaporation surface.
