Abstract:
A generator cell (10) includes a high voltage assembly (12) having a high voltage electrode (24), a low voltage assembly (14) having a low voltage electrode (102), a barrier dielectric (28, 92) between the electrodes defining a discharge region (110) for producing a reactive gas, and a welded seal joining the assemblies to create a permanently sealed chamber between the assemblies including the discharge region. The generator cell may have a gap in the discharge region (110) of 0.005 inch or less. The cells may be modularly combined to form a reactive gas generator system.
Abstract:
Plasma ignition and cooling methods are described. A method can include providing a dielectric toroidal vessel (1510), at least one ignition electrode (1530) adjacent to the vessel, and a heat sink having multiple segments (1530) urged toward the vessel by a spring-loaded mechanism, and a thermal interface between the vessel and the heat sink. Another method can include providing a gas having a flow rate and a pressure and directing a portion of the flow rate of the gas into a vessel channel (1541-1542). The gas is ignited in the channel while the remaining portion of the flow rate is directed away (1571;1552) from the channel (1541-1542).
