Filed:

May 29, 2009

Appl. No.:

12/995114

Inventors:

Cameron A. Moore - Loveland CO, US
Douglas A. Scott - Laporte CO, US
George J. Collins - Ft. Collins CO, US

Assignee:

Colorado State University Research Foundation - Fort Collins CO

International Classification:

H05B 31/26

US Classification:

31511121, 31511151, 31511191

Abstract:

A plasma generating system, related method and device are disclosed. The plasma generation system includes a plasma generation device, a source of ionizable gas and a driver network. The plasma generation device includes a housing, an electrode, and a resonant circuit. The housing includes a passage defined therein and directs a flow of ionizable gas therethrough. The electrode is coupled to the ionizable gas flowing through the passage of the housing. The resonant circuit includes a capacitor and an inductor connected together in series. The resonant circuit has a resonance frequency and is coupled to the electrode. The resonant circuit receives an AC signal. The driver network provides the AC signal such that the AC signal has a frequency and excites the ionizable gas flowing through the passage of the housing to a plasma.

International Classification:

H05H 1/24
H01J 17/26

US Classification:

31511121, 31323131

Abstract:

The present disclosure provides for a plasma system. The plasma system includes a plasma device, an ionizable media source, and a power source. The plasma device includes an inner electrode and an outer electrode coaxially disposed around the inner electrode. The inner electrode includes a distal portion and an insulative layer that covers at least a portion of the inner electrode. The ionizable media source is coupled to the plasma device and is configured to supply ionizable media thereto. The power source is coupled to the inner and outer electrodes, and is configured to ignite the ionizable media at the plasma device to form a plasma effluent having an electron sheath layer about the exposed distal portion.

Abstract:

The present disclosure provides for a plasma system including a plasma device coupled to a power source, an ionizable media source and a precursor source. During operation, the ionizable media source provides ionizable media and the precursor ionizable media source provides one or more chemical species, photons at specific wavelengths, as well as containing various reactive functional groups and/or components to treat the workpiece surface by working in concert for synergetic selective tissue effects. The chemical species and the ionizable gas are mixed either upstream or midstream from an ignition point of the plasma device and once mixed, are ignited therein under application of electrical energy from the power source. As a result, a plasma effluent and photon source is formed, which carries the ignited plasma feedstock and resulting mixture of reactive species to a workpiece surface to perform a predetermined reaction.
