Abstract:
1. An assembly for plasma generation comprising: (a) a cathode plate comprising a fixed cathode tip, said cathode tip being an integral part of said cathode plate; (b) at least one cascade plate; (c) at least one separator plate disposed between said cathode plate and said cascade plate; (d) an anode plate; and (e) an inlet for gas; wherein the cathode plate, the at least one cascade plate, the at least one separator plate, and the anode plate each comprises internal cooling channels, wherein the internal cooling channels are connected to one another through coaxial bores defined in each of the cathode, cascade, separator and anode plates, wherein portions of the internal cooling channels define a plurality of loops for a cooling medium between at least one inlet and at least one outlet, one loop of said plurality of loops being located within each of the cathode plate, the separator plate, the cascade plate and the anode plate; wherein said cathode plate, separator plate, cascade plate and anode plate define a stacked construction of plates upon one another and are “electrically isolated” from one another, and wherein said electrically isolated cathode plate, separator plate, and cascade plate define a plasma generation chamber, said cathode tip being disposed within said plasma generation chamber.
