The invention relates to a method for operating an arc source, whereby an electric spark discharge is ignited and run on the surface of a target and the spark discharge is simultaneously fed a direct current with an associated constant voltage DV as well as a pulsed current generated by a periodically applied voltage signal. The voltage at the arc source is boosted over several microseconds and the shape of the voltage signal is in essence arbitrarily selectable. |
