Abstract
A gas discharge vessel and a process for extending the life of a gas discharge vessel, which is used as a radiation source, is permeable to radiation of a wavelength from 10 to 1,000 nm and has an activated cathode, wherein a metal oxide, of which the free enthalpy .DELTA.G, under the pressure and temperature conditions prevailing in the vessel, is both greater than the free enthalpy of the oxides, from which the vessel is constructed, and greater than the free enthalpy of any oxide or suboxide of the element constituting the activating substance applied to the cathode is introduced in the discharge path.
