    摘要： A filament for an X-ray tube has a varied wire diameter but has a constant coil outside diameter to obtain a good uniformity of the longitudinal temperature distribution of the filament. The filament has a wire diameter d which is gradually reduced from the longitudinal central region to the longitudinal ends while the coil outside diameter D is fixed along the longitudinal direction. The wire is polished at only the inside of the coil to reduce the wire diameter. In order to make the longitudinal temperature distribution uniform as far as possible, the difference Δd between the wire diameter dmax at the longitudinal central region and the wire diameter dmin at the longitudinal ends should satisfy the following limitation: Δd/dmax=0.041 to 0.145.

    摘要： An improved thermionic electric converter uses a wire grid cathode to provide a larger surface area for electrons to boil off. Alternately or additionally, the larger electron emission surface area can be achieved by using a curved electron emission surface. A laser provides quantum interference to electrons just before they reach the anode, thereby lowering their energy levels such that they more readily are captured by the anode. The arrangement provides improved conversion efficiency and reduced electron scatter.

    摘要： A high power electron beam machine for operating on a workpiece is disclosed in which the beam focus is automatically maintained constant without the necessity of lens current variation regardless of changes in beam current. The electron gun assembly for the machine consists of a Rogowski gun having a square ribbon filament recessed from an enlarged filament aperture, and a pin type anode with a reduced height and an increased gap from the bias electrode. The electron gun produces a stationary image or apparent source of electrons even though the beam current or the high voltage operating level of the electron gun is varied. Increased life of the ribbon filament is obtained by using a ribbon filament consisting of tungsten with 3 percent rhenium added thereto.

    摘要： First and second sets of thermionic cathode emitter filaments are wound into a composite cross-wound helical cathode emitter structure. The helical cathode emitting structure is supported at opposite ends by means of electrical terminals for passing electrical current through the cross-wound filaments. At one end of the composite mesh, the filaments have inwardly directed terminal portions terminating on the terminal support structure, whereby the inwardly directed terminal portions of the filaments permit a certain degree of flexibility to accommodate unequal thermal expansion of the support and mesh and whereby the cooling effect of the terminal structure is generally limited to the inwardly directed terminal portions of the filaments. The terminal structure also includes flexible support fingers to further accommodate unequal thermal expansion.

    摘要： An electrode component for generating large area atmosphere pressure plasma is provided. The electrode component comprises a first transparent insulation substrate, a first transparent electrode pattern, a second transparent electrode pattern, and a second transparent insulation substrate. The first transparent insulation substrate has a first thickness. The first transparent electrode pattern and the second transparent electrode pattern are formed on the upper surface of the first transparent insulation substrate and has a gap therebetween. The second transparent insulation substrate has a second thickness and covers the first transparent electrode pattern and the second transparent electrode pattern. The first thickness is greater than the second thickness in order to form atmospheric pressure plasma above the second transparent insulation substrate.
