    Abstract: A microdischarge device that includes one or more electrodes encapsulated in a nanoporous dielectric. The devices include a first electrode encapsulated in the nanoporous dielectric and a second electrode that may also be encapsulated with the dielectric. The electrodes are configured to ignite a microdischarge in a microcavity when an AC or a pulsed DC excitation potential is applied between the first and second electrodes. The devices include linear and planar arrays of microdischarge devices. The microcavities in the planar arrays may be selectively excited for display applications.

    Abstract: The design and manufacturing processes for Hollow Cathode Assemblies (HCA's) that operate over a broad range of emission currents up to 30 Amperes, at low potentials, with lifetimes in excess of 17,500 hours. The processes include contamination control procedures which cover hollow cathode component cleaning procedures, gas feed system designs and specifications, and hollow cathode activation and operating procedures to thereby produce cathode assemblies that have demonstrated stable and repeatable operating conditions, for both the discharge current and voltage. The HCA of this invention provides lifetimes of greater than 10,000 hours, and expected lifetimes of greater than 17,500 hours, whereas the present state-of-the-art is less than 500 hours at emission currents in excess of 1 Ampere. Stable operation is provided over a large range of operating emission currents, up to a 6:1 ratio, and this HCA can emit electron currents of up to 30 Amperes in magnitude to an external anode that simulates the current drawn to a space plasma, at voltages of less than 20 Volts.

    Abstract: Systems and methods presented herein are generally directed to enhancing electrical discharge. A hollow conical electrode may be provided to discharge electrical energy in a directed manner. The conical electrode has two openings: a larger entrance opening; and a smaller exit opening. These openings are configured to allow radiated energy to pass therethrough and form a preferential path of electrical conduction. The larger entrance opening has a surface with a radius of curvature that is larger than that of the second smaller exit opening. The smaller exit opening directs electrical energy to the path because of stronger electric fields. In one embodiment, a protruding electrode element is configured with the smaller exit opening to further enhance electrical discharge by focusing electric fields in the vicinity of the protruding electrode.

    Abstract: The cavity 102 defines an empty volume formed in the insulator 108 has its walls defined by the insulator 108 and may extend through either (or both) the first electrode 106 or the second electrode 104, in which case the first electrode and/or second electrode also define the walls of the cavity 102. The cavity 102 is preferably cylindrical and has a diameter of 0.1 μm-1 mm. More preferably, the diameter ranges from 0.1 μm-500 μm, 1 μm-100 μm, or 100 μm-500 μm. The cavity 102 will be filled with a gas that contacts the cavity walls, fills the entire cavity 102 and is selected for its breakdown voltage or light emission properties at breakdown. Light is produced when the voltage difference between the first electrode 106 and the second electrode 104 creates an electric field sufficiently large to electrically break down the gas (nominally about 104 V-cm). This light escapes from the microcavity 102 through at least one end of the cavity 102.

    Abstract: In accordance with one embodiment, the hollow cathode is comprised of a first tantalum tube, tantalum foil, and a second tantalum tube. The foil is in the form of a spiral winding around the outside of the first tube and is held in place by the second tube, which surrounds the foil. One end of the second tube is approximately flush with one end of the first tube. The other end of the second tube extends to a cathode support through which the working gas flows. To start the cathode, a flow of ionizable inert gas, usually argon, is initiated through the hollow cathode and out the open end of the first tube. An electrical discharge is then started between an external electrode and the first tube. When the first tube is heated to operating temperature, electrons are emitted from the open end of the first tube.
