Title: COAXIAL TUBE COUPLING

Abstract

BS>This patent shows a device for quickly coupling coaxial tubes in metal-to-metal fashion, so as to be suitable for use in a nuclear reactor. A threaded coliar urges a tapered metal extension on the outer coaxial tube into a tapered seat in the device and simultaneously exerts pressure through a coaxial helical spring so that a similar extension on the inner tube seats in a similar seat near the other end.

  • A quartz laser tube for use with a metal, or metal halide, laser media employs a coaxial electrical connection in which a longitudinal discharge in the laser medium serves as the central conductor, and the ground return path is a cylindrical metal container which surrounds the laser discharge. This arrangement minimizes the circuit inductance for a given longitudinal discharge, and the outer metal cylinder serves both as a heat shield and a ground shield for reducing electrical noise radiation. Optical access in the longitudinal direction is provided by cylindrically-symmetrical electrode/window assemblies attached to either end of the quartz laser dischargemore » tube.« less
  • A medium-gain photomultiplier tube having high current output, fast rise- time, and matched output impedance was developed. The photomultiplier tube comprises an elongated cylindrical envelope, a cylindrical anode supported at the axis of the envelope, a plurality of elongated spaced opaque areas on the envelope, and a plurality of light admitting windows. A photo-cathode is supported adjacent to each of the windows, and a plurality of secondary emissive dynodes are arranged in two types of radial arrays which are alternately positioned to fill the annular space between the anode and the envelope. The dynodes are in an array being radiallymore » staggered with respect to the dynodes in the adjacent array, the dynodes each having a portion arranged at an angle with respect to the electron path, such that electrons emitted by each cathode undergo multiplication upon impingement on a dynode and redirected flight to the next adjacent dynode.« less
