Claim Text:
1. A vacuum arc vaporization source comprising: a ring-shaped magnetic field source; a cathode body, comprising a vaporization material, being structured and arranged as a cathode for production of an arc discharge on a vaporization surface of the cathode, wherein the cathode body is axially bounded in a first axial direction by a cathode base and in a second axial direction by the vaporization surface; the ring-shaped magnetic field source being arranged polarized parallel to or anti-parallel to a surface normal of the vaporization surface, concentric to the surface normal of the vaporization surface, and spaced at a predeterminable first distance from the vaporization surface on a side of the cathode body remote from the cathode base; a magnetic field enhancement ring being arranged on a side of the cathode body remote from the vaporization surface and spaced at a predeterminable second distance from the cathode base, wherein an internal diameter of the magnetic field enhancement ring amounts up to 50% of a diameter of the cathode.
