Definitions

  • the present invention relates to gaseous electric discharge devices generally and ⁇ more particularly the invention relates to such devices of the positive column type in which the g seous electric 1,5 a chamber in the interior of the glass container of the device.
  • a filamentary incandescent elec- .trode is arrangedv in said chamber, said electrode being the cathode.
  • 'I'he anode is placed outside said chamber and in close proximity to the mouth v of a small diameter tube in" the walls of said chamber, the open end of said tube being above l the lamentary electron emitting cathode.
  • The/ greater part of the discharge path is covered by the metal chamber and it extends from the cathode through the constricted tubel tothe anode.
  • K Fig. 1 is a side elevational view of the invention
  • 'F Fig. 2 is a front elevational view of thestem
  • I I is a laterally protruding tube I1 of small diameter located above the cathode I2 and atA the greatest possible distance from said cathode I2,
  • the anode I8 is 5 located underneath the end of the tube I1 in the container I said anode I8 being atransverse wire (Fig. 2) attached to a metal support I9 which is sealed into stem 2 and connected to lead 1.
  • Container I is filled with the usual discharge conduct- 10 ing gases such as rare gases, or mixtures of such gases with common gases or metal vapors.
  • cathode I2 is iirst heated by connecting leads 5, 6 into the circuit.
  • cathode I2 is heated to an electron emittingA tem- 15 perature one of the leads 5, 6 is disconnected from the current source.
