Abstract (en)

[origin: EP0800201A2] In an excimer emitter with a halogen-containing gas-filled discharge space, the halogen content of the discharge space (16) is ≥ 1 x 10<-10>, preferably 1 x 10<-10>-1 x 10<-5>) mol/cm<3> per cm<2> of its interior surface and is also adjusted in accordance with the maximum power density (in W/cm of emitter length) of the emitter (11) to a value of 1 x 10<-7>-1 x 10<-5> mol/cm<3> per unit power density. Also claimed are: (i) the production of a long life excimer emitter as above, in which the interior surfaces of the discharge space (16) are exposed to a halogen-containing passivating gas, preferably chlorine, prior to gas filling; (ii) a process for extending the life of an excimer emitter, having a halogen-containing gas-filled discharge space, by exposing the discharge space (16) to IR radiation or by releasing halogen from a halogen reservoir (17) located in the discharge space (16); and (iii) an apparatus for carrying out the above processes (i) and (ii).
