Abstract

We report an experimental study of the operating characteristics of an air-cooled, high-pressure argon excimer VUV lamp (~126nm), driven by a dielectric barrier discharge (DBD), in the regime of high electrical power loadings close to the thermal loading limit. Remarkably, under such conditions, the VUV output is seen to reach a maximum a few seconds after turn-on, and thereafter decrease by ~50% within a few minutes. Although the rate of decrease in the VUV output is shown to be matched in part to the thermally induced rate of gas expansion from the plasma region, we propose this VUV “spiking” behaviour is similar to that reported by Gerasimov (Opt. & Spectros. 83, 534, 1997) for an interrupted discharge in a liquid N2 cooled excimer lamp.
