Patent ID: 8471171

Claim:
A device for the creation of a high pressure plasma jet, comprising: a first electrode; a second electrode, spaced from the first electrode; wherein the first and second electrodes define at least one microhollow through the first electrode and the second electrode that is 0.1-1.2 mm wide; 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 direct current for producing microhollow discharges in each of the at least one microhollow formed through the first electrode and the second electrode; a gas supply for supplying gas into each of the at least one microhollow at the second electrode so as to create a gas plasma exiting the at least one microhollow at the first electrode, wherein the gas is selected from the group consisting of air, noble gasses, molecular gasses, and mixtures thereof; wherein the first electrode is separated from the second electrode by a dielectric defining at least one microhollow formed through the dielectric, in line with at least one microhollow through the first electrode and the second electrode; and wherein the gas supply for supplying gas into each of the at least one microhollow at the second electrode supplies gas at a flow rate at or between about 50 ml per minute to about 12 liters per minute.
