    Abstract: A method for fabricating microcavity discharge devices and arrays of devices. The devices are fabricated by layering a dielectric (1020, 220) on a first conducting layer or substrate (210, 1010). A second conducting layer or structure is overlaid on the dielectric layer. In some devices, a microcavity (1040, 212) is created that penetrates the second conducting layer or structure and the dielectric layer. In other devices, the microcavity penetrates to the first conducting layer. The second conducting layer or structure together with the inside face of the microcavity is overlaid with a second dielectric layer. The microcavities are then filled with a discharge gas. When a time- varying potential of the appropriate magnitude is applied between the conductors, a microplasma discharge is generated in the microcavity. These devices can exhibit extended lifetimes since the conductors are encapsulated, shielding the conductors from degradation due to exposure to the plasma. Some of the devices are flexible and the dielectric can be chosen to act as a mirror.

Beschädigung des inneren Kanals das System verlässt.

    Abstract: The invention concerns cold electrodes for gas discharges with an electrically conductive carrier material (1) on which an emission coating (3) is disposed, the photoelectric output work of the material of the emission coating (3) being less than that of the carrier material (1) or less than 5.6*10 joule/electron. The emission coating (3) can in particular contain yttrium. The electrode preferably has the form of a hollow body and can be embedded in a glass body (8).

    Abstract: A hollow cathode type light source is provided having improved operating stability by forming the cathode of an alloy of a highly reactive, unstable prime metal of interest for spectral emission, and of a chemically stable, readily sputtered metal. An alloy of silver and calcium with a small amount of magnesium provides a hollow cathode device which exhibits stable operation after a minimum warm-up time.

    Abstract: The use of the electride form of 12CaO-7Al2O3, or C12A7, as a low work function electron emitter in a hollow cathode discharge apparatus is described. No heater is required to initiate operation of the present cathode, as is necessary for traditional hollow cathode devices. Because C12A7 has a fully oxidized lattice structure, exposure to oxygen does not degrade the electride. The electride was surrounded by a graphite liner since it was found that the C12A7 electride converts to it's eutectic (CA+C3A) form when heated (through natural hollow cathode operation) in a metal tube.
