Abstract

The results of investigations of dielectric barrier discharges parameters and UV-emission of Xe/SF₆ (50:1) mixture related to the pressure and the distance between electrodes are presented. The basic source of UV-emission in Xe/SF₆ mixture is XeF^* excimer, whose emission band center is positioned at 354 nm. The mixture pressure was varied in the range from 40 to 180 Torr, and the distance between electrodes changed in range from 3 to 11 mm. The distance between the electrodes and the gas pressure were selected out so that pd-product should be constant. The experiments conducted display that for pd = const in the pressure range of 70-180 Torr there are some regularities which are partly similar to the scaling laws of gas discharge, namely: the current density ~ const; the power dissipated by the discharge ~ 1/p^0.3; UV emission power ~ 1/p; the efficiency of lamp ~ 1/p^0.8; the current pulse duration ~ 1/p^0.3. The highest efficiency (6-8%) was reached for 30-50 Torr gas pressure.
