    Abstract: The faceplate of a light detector tube is provided with an internal photocathode having wedge-shaped projections and external lenses to concentrate the light from a source onto the projecting photosensitive surface areas. An accelerating grid having a corresponding configuration is spaced closely to the photocathode to increase the emission of electrons from the photosensitive surface. A potential source establishes an electric field between the photocathode and an anode, with the anode collecting the electrons.

    Abstract: An index grating for use in measuring apparatus in which relative movement between the index grating and a scale grating is monitored, consisting of a regular series of alternate transparent and opaque regions, the opaque regions constituting parts of a solid state photocell. There is also described a reading head incorporating such an index grating.

    Abstract: The envelope of the image intensifier is principally a glass cylinder closed at one end to support the viewing screen and having a sealing land at the other end with a series of apertures spaced thereabout. This end of the envelope is closed by a glass cap secured to the sealing land by a glass to glass seal. The photocathode has a supporting frame dimensioned to be positioned within the principal envelope section and having threaded mounting bushings in radial alignment with the apertures in the sealing land of the envelope, respectively. Mounting pins inserted through the openings of the envelope thread into these bushings and mechanically secure the photocathode in position. Each pin is sealed to the envelope in a vacuum-tight seal. In manufacturing the image intensifier three tubulations are affixed to the envelope, being spaced about the viewing screen thereof, and a fixture having three tines is inserted through these tubulations into the envelope and advanced toward the sealing land. The pickup pack is rested on the ends of these tines and the fixture is then withdrawn to draw the pickup pack away from the sealing land where it remains until the cap is sealed to the principal envelope section. Thereafter, the fixture is advanced once more to bring the mounting bushings of the pickup pack into alignment with the apertures on the sealing land for the purpose of receiving the mounting pins.

    Abstract: A multichannel electron multiplier has a plurality of multiplying stages. Each stage is formed from a flat plate of secondary electron emissive material slit into a plurality of fingers. Alternate fingers are twisted out of the plane of the plate at right angles thereto. The twisted fingers in successive stages are staggered to provide a plurality of zigzag electron multiplying channels. The source of electrons to be multiplied in a photo-electron emissive cathode and light is focused or collimated onto the photocathode at positions corresponding to the multiplying channels. In a second embodiment, the faceplate of a multiplier tube is a fibre optics plate and light is directed onto it by fibre optics light guides to positions corresponding to the multiplying channels. A focusing electrode is disposed between the photocathode and the first multiplying stage and serves to focus electrons onto the twisted fingers. The non-twisted fingers also help to focus electrons onto the twisted fingers in successive multiplying stages along the multiplying channels.

    Abstract: An ultraviolet sensitive gaseous discharge detector has an essentially uniform 360* angular sensitivity. The detector has first and second anodes and a cathode which are aligned in a common plane. The first and second anodes have elongated crosssections, with the elongated surfaces of the first and second anodes being aligned essentially parallel to the common plane. The cathode has an essentially circular cross-section and is disposed between the first and second anodes.
