An oxygen plasma generated by a linear multiorifice hollow cathode (LMHC) is used for oil removal from metal strips. To operate the source with a DC power the cathode is constructed from stainless steel. The source has a power limit that determined by cathode overheating and consequential appearance of arcs that destroy the cathode. Stainless steel replacement by aluminum would substantially improve cathode cooling and increase the power limit. Unfortunately DC discharge in oxygen with an aluminum cathode is accompanied with arcing. One way to avoid arcing in to use pulse-power. In this work, pulse-power hollow cathode discharge is investigated. Pulse durations and frequency influences on an oxygen plasma generated in various hollow cathodes are studied. Implementation of pulse-powered aluminum hollow cathode for oil removal is discussed.
