Definitions

  • the invention relates to a flash lamp with two electrodes sealed in a gas-tight manner from tempered glass.
  • the invention has for its object to provide a flash lamp, the load capacity is increased compared to the prior art, d. H. which has a higher energy density compared to the known flash lamps.
  • composition of the hard glass is selected so that the components which evaporate during the discharge are at least partially emitter substances which reduce the work function at the cathode.
  • the easily evaporating components of the hard glass are deposited on the cathode without the energy density being reduced thereby. An increase is even possible.
  • a flash lamp is shown with a glass tube 1 made of tempered glass, at the ends of which an anode 2 and a cathode 3 are sealed in a gas-tight manner.
  • the interior 4 of the flash lamp is filled with xenon.
  • the cathode 3 is connected to a cathode body 5 and the anode 2 to an anode body 6.
