A plasma generator having a dielectric body; a first end wall and a second end wall attached or coupled to each end of the dielectric body to define a cavity within the dielectric body, and wherein the second end wall includes at least one discharge aperture formed therein; at least one gas inlet formed proximate the first end of the dielectric body; at least one anode located within the cavity of the dielectric body, wherein the at least one anode includes at least one anode aperture; at least one hollow discharge nozzle associated with each discharge aperture, and extending from the second end wall to a nozzle aperture, such that when a generated plasma is produced, the generated plasma flows through each discharge aperture, each associated discharge nozzles, and each associated nozzle aperture; and at least one cathode formed at least substantially around a portion of each discharge nozzle.

Low temperature plasma generator

A plasma generator for delivering a generated plasma to an area that is a distance from the area where the plasma is initially generated, including a dielectric tube portion extending from a gas inlet to a discharge aperture; an anode formed at least substantially around a portion of the discharge tube, wherein the anode is electrically coupled, via an electrical connection, to a power supply; a cathode formed at least substantially around a portion of the discharge tube, wherein the cathode is electrically coupled, via an electrical connection, to the power supply; and an elongate discharge tube attached or coupled to the discharge aperture such that when a generated plasma is produced, the generated plasma flows through the discharge tube.

Low temperature plasma generator having an elongate discharge tube

A plasma generator, comprising a dielectric tube having a first end and a second end, wherein the first end is sealed, but for a gas inlet; at least one first dielectric disk located within the dielectric tube, wherein the first dielectric disk includes at least one first dielectric aperture formed therein; a first ring electrode that at least partially surrounds the at least one first dielectric aperture and is electrically coupled 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; and a second ring electrode that at least partially surrounds the at least one second dielectric aperture and is electrically coupled to the power supply. During use, the plasma generator produces at least one plasma plume that is launched into open air.

Plasma generator

An electrodeless excimer UV lamp, comprising an enclosed chamber with a gas sealed within the enclosed chamber, wherein the gas is capable of being used to generate a plasma discharge, a first electrode wrapped around the outer surface of the chamber at a first location, a second electrode wrapped around the outer surface of the chamber at second location, and a power supply configured to apply a voltage to the first electrode and the second electrode. During operation of the UV lamp, a plasma discharge is generated by applying a voltage to the electrodes wrapped around the outer surface of the chamber to ignite the gas or gas mixture inside the chamber and generate a plasma discharge within the chamber, such that a specific wavelength of UV radiation will be generated by the particular gas within the chamber.
