Abstract:
In electron beam discharge tubes breakdown in the form of a gaseous arc can occur. An improved form of electrode which protects an insulating support against local high-stress fields is described. The electrode has a conductive shield extending to the other side of an interface between the electrode and the insulating support. A mechanism, the "single surface multipactor effect," which could cause the breakdown is also described.
Abstract:
Gas discharge panel conductor configuration and conductor system to increase efficiency of light output conductor configuration which is substantially more likely to be electrically continuous. The conductors of a conductor array on a plate forming the viewing side of the panel are formed by sets of coplanar conductor elements spaced apart so that when a discharge occurs, an observer sees more of the center of the discharge which would ordinarily be partially hidden by a solid conductive line on the viewing side of the panel. The conductor elements of a set may be connected at regular intervals to provide a plurality of electrically parallel routes for conduction in case a section of a conductor element of a set is discontinuous. The gas discharge is more visible since the applied field between selected conductor elements is across two conductors which are not congruent as seen by the observer. Moreover, since the conductor elements are relatively narrow fringe light produced at a discharge site is better seen as to further enhance the delivery of light from the panel. Consult the specification for other features and details.

The shadow-mask frame includes a lip cooperating with raised portions on the shields to insure flexure of the bowed edges during installation.
Abstract:
Shields for feedthrough pin insulators of a hot cathode ionization gauge are provided to increase the operational lifetime of the ionization gauge in harmful process environments. Various shield materials, designs, and configurations may be employed depending on the gauge design and other factors. In one embodiment, the shields may include apertures through which to insert feedthrough pins and spacers to provide an optimal distance between the shields and the feedthrough pin insulators before the shields are attached to the gauge. The shields may further include tabs used to attach the shields to components of the gauge, such as the gauge's feedthrough pins. Through use of example embodiments of the insulator shields, the life of the ionization gauge is extended by preventing gaseous products from a process in a vacuum chamber or material sputtered from the ionization gauge from depositing on the feedthrough pin insulators and causing electrical leakage from the gauge's electrodes.
