The electrical contact may include a conductive pad in electrical contact with the electrode and/or the plasma-shell.
Abstract:
A spark gap switch for high power ultra-wideband electromagnetic wave radiation is provided. The spark gap switch includes a casing, electrodes, brackets and an electrode protrusion. Openings are formed in respective opposite ends of the casing. The electrodes are installed in the casing at positions spaced apart from each other in such a way that the electrodes face each other and are disposed inside the openings. The brackets are installed in the respective openings of the casing. The brackets fasten rear ends of the corresponding electrodes to the casing. The electrode protrusion is provided on a central portion of at least either of the electrodes to induce stabilized discharge. The maximum diameter of the electrodes is smaller than the inner diameter of the casing so that the circumferential outer surfaces of the electrodes do not make contact with the circumferential inner surface of the casing.
Abstract:
An embodiment of the invention is a microtip microplasma device having a first metal microtip opposing a second metal microtip with a gap therebetween. The first and second metal microtips are encapsulated in metal oxide that electrically isolates and physically connects the first and second metal microtips. In preferred devices, the first and second metal microtips and metal oxide comprise a monolithic, unitary structure. Arrays can be flexible, can be arranged in stacks, and can be formed into cylinders, for example, for gas and liquid processing devices, air filters and other applications. A preferred method of to forming an array of microtip microplasma devices provides a metal mesh with an array of micro openings therein. Electrode areas of the metal mesh are masked leaving planned connecting metal oxide areas of the metal mesh unmasked. Planned connecting metal oxide areas are electrochemically etched to convert the planned connecting metal oxide areas to metal oxide that encapsulates opposing metal microtips therein. The mask is removed. The electrode areas are electrochemically etched to encapsulate the electrode areas in metal oxide.

A cathode sub-assembly is comprised of a retainer, a cathode and a collar, each of which has smooth unthreaded surfaces that slidably engage each other. A shield serves to hold the sub-assembly in a support plate. The cathode projects from the sub-assembly into an arc chamber with a tortuous path created therebetween for passage of a plasma flow.
