Patent ID: 7572998

Claim:
A device for the creation of a high pressure plasma jet, comprising: a first electrode; a second electrode, spaced from the first electrode; at least one microhollow formed through the first electrode and the second electrode; a circuit for creating an electrical potential between the first electrode and the second electrode, such that the first electrode is a cathode and the second electrode is an anode, at a voltage and current for producing microhollow discharges in each of the at least one microhollow formed through the first electrode and the second electrode, wherein the microhollow is tapered such that the area of the microhollow disposed in the second electrode is larger than the area of the microhollow disposed in the first electrode; and a gas supply for supplying gas into each of the at least one microhollow at the second electrode so as to create a plasma jet exiting the at least one microhollow at the first electrode.
