    摘要: A tubular glow discharge electrode is formed therein with a slot in which front end parts of support leads are inserted. The slot has a widened center part which defines an opening. The tube-like glow discharge tube is welded at its one end part to one of the support lead so as to be electrical conductive to the same, and is caulked at it's the other end part to the other one of the support leads through the intermediary of an insulator. A filament electrode (ark discharge electrode) carrying an electron-emissive substance is supported to the free end parts of the support leads within the tube-like glow discharge electrode which therefore surrounds the arc discharge electrode with a small gap defined between the glow discharge electrode and the filament electrode. In this arrangement, particles of the electron-emissive substance evaporated and scattered from the filament electrode are soon trapped to the inner surface of the glow discharge electrode without being emitted from the glow discharge electrode, and can be reused as the electron-emissive substance, thereby it is possible to prolong the use life of the electron device.

    摘要: An electric gas discharge lamp includes an electrode having a tip portion comprised by a mesh body carrying an emitter material. The mesh body in a favorable embodiment is circular cylindrical and is attached via an electrically conductive thermal isolator to a conductive feed-through, such as a hollow ferrule, extending through a seal of the lamp vessel. As compared to a continuous walled tip portion of similar shape and material, the mesh body has a lower mass and heat capacity, and can therefore be operated at higher temperatures without increasing the temperature of the seal area. The higher operating temperature of the tip portion promotes greater electron emission from the emitter material, and therefore a lower cathode fall. A lower cathode fall enables the lamp to be operated at higher lamp currents for greater light output. The mesh body also has the capability to reduce sputtering from the electrode through improved adhesion of the emitter material to the tip portion and faster attainment of its nominal operating temperature as compared to a smooth continuous walled body. In a favorable embodiment, the lamp is a low pressure discharge lamp having an inside diameter of less than about 5 mm.

    摘要: A unique cathode (30) for an ultraviolet discharge lamp (10) is described. The cathode includes a triple-coil wire, i.e., the wire has a primary coil (43), a secondary coil (41) wound around the primary coil and a tertiary coil (36) wound around the secondary coil. The interstices of the primary coil and secondary coil, but not the tertiary coil, are occupied by a crystalline oxide emitter material. Filling the primary and secondary coils of the triple coil cathode provides a cathode having a greater amount of emitter material than prior art. In addition, as the outer layer of the emitter material sputters away from bombardment by positive ions, the remaining emitter material is protected by the now-exposed portion of the coil wire which protrudes beyond the remaining emitter material. Thus, incoming positive ions are apt to strike the exposed wire, and not the remaining emitter material.

    摘要: A discharge device for operation in a gas at a prescribed pressure includes a cathode having a plurality of micro hollows therein, and an anode spaced from the cathode. Each of the micro hollows has dimensions selected to produce a micro hollow discharge at the prescribed pressure. Preferably, each of the micro hollows has a cross-sectional dimension that is on the order of the mean free path of electrons in the gas. Electrical energy is coupled to the cathode and the anode at a voltage and current for producing micro hollow discharges in each of the micro hollows in the cathode. The discharge device may include a discharge chamber for maintaining the prescribed pressure. A dielectric layer may be disposed on the cathode when the spacing between the cathode and the anode is greater than about the mean free path of electrons in the gas. Applications of the discharge device include fluorescent lamps, excimer lamps, flat fluorescent light sources, miniature gas lasers, electron sources and ion sources.
