Abstract

We investigated Xe- N2 gas discharge primarily as a source of vacuum ultraviolet for florescent lamps. The discharge performances of Xe based nitrogen admixture gas are improved when compared with the results of pure Xe discharge. The experimental results come from investigating the Xe positive column and were determined by measuring the infrared radiation during the discharge operation. These results suggest that the integrated infrared area is increased by about 40% under optimal conditions. This efficiency increase occurs because low energy electrons contribute to the production of exited nitrogen, which can excite Xe gas.
