  • Gas discharge closing switch with unitary ceramic housing
    Patent number: 5550430
    Abstract: A gas discharge closing switch, such as a thyratron, has a one-piece ceramic housing containing an anode, a cathode, and a control electrode. The anode and cathode form fluid-tight seals with opposite ends of the housing. The control electrode is mounted entirely within the housing, and, in one embodiment, is affixed to an interior wall of the housing. The housing preferably supports the anode, the cathode and the control electrode, and maintains electrical isolation between them.

  • Multiple surface high voltage structure for a gas discharge closing switch
    Patent number: 5545947
    Abstract: A gas discharge closing switch has a high voltage anode structure containing a plurality of surface elements facing substantially toward a cathode and spaced from each other to define gaps therebetween. In a preferred embodiment, a control electrode structure includes a surface defining an aperture corresponding to at least one of the gaps.
