A sputter ion source includes an ionizer; a sputter cathode, including a cathode, a sputter insert, and a shielding cap; a forming electrode; cathode insulator; a hollow, cylindrical shielding cathode, surrounding the sputter cathode, and tapered rotationally symmetrically in the region of the sputter insert; and a vacuum-tight housing for enclosing all of the foregoing. The sputter ion source has a prolonged operating life, low maintenance costs, and prevents atomization of parts of the ion source, for generating negative ions, in the vicinity of the cathode insert.
