Abstract:
1. A plasma generator, comprising: a dielectric tube having a first end and a second end, wherein the first end is sealed; a gas inlet formed proximate the first end of the dielectric tube; at least one first dielectric disk located within a cavity of the dielectric tube, wherein the first dielectric disk includes at least one first dielectric aperture formed therein; a first ring electrode coupled to the first dielectric disk such that the first ring electrode at least partially surrounds the at least one first dielectric aperture, wherein the first ring electrode is electrically coupled, via an electrical connection, to a power supply; at least one second dielectric disk located proximate the second end of the dielectric tube, wherein the second dielectric disk includes at least one second dielectric aperture formed therein such that a plasma plume may extend from the at least one second dielectric aperture; a second ring electrode coupled to the second dielectric disk such that the second ring electrode at least partially surrounds the at least one second dielectric aperture, wherein the second ring electrode is electrically coupled, via an electrical connection, to the power supply.
