Definitions

  • the pressure of the gas filling can be only 0.1 to 0.8 10 mm. of mercury. Any absorption of the gas is therefore of significant importance and for example, it is found that an argon filling of 0.8 lmm. of mercury is absorbed in a few hours.
  • the low ionisation voltage of the mercury results in substantially mercury ions being produced and the xenon atoms remain comparatively unaffected.
  • the mercury atoms which are flung into the walls may be easily replaced from a small drop of mercury lying on the bottom of the rectifier.
  • a certain percentage of the xenon atoms are brought to a meta-stable level whose energy amounts to 8.28 to 9.40 electron volts.
  • these long living, meta-stable xenon atoms are not capable of ionising'mercury atoms which have the ionisation voltage 10.85 electron volts.
  • an argon filling would produce a certain number of mercury ions durin the blocking time of the rectifier and these mercury ions in turn produce argon ions by impact, which ions are caught by the field and neutralized on the walls.
  • a high-tension electric discharge rectifier tube comprising a container and a gaseous filling consisting of Xenon and mercury vapor, the xenon being present in an amount equivalent to a pressure of 0.1 to 0.8 10- millimeters of mercury
