Abstract

A type of plasma discharge that propagates along the surface of a resistive barrier composed of an electrolyte in water is described. Electric fields parallel to the surface appear to steer the discharge in the direction of a submerged anode to produce a propagating plasma front that travels a distance of 20 cm or more along a trough, at a rate of ~10 ms^-1. The plasma´s optical spectrum shows the presence of excited OH radicals, and the relatively high energy density of the plasma indicates possible usefulness for industrial applications.
