Abstract

AbstractA description is given of an experimental arrangement for studying xenon pulse discharges with high specific power dissipation. By means of time resolved measurements of discharge pressure and spatial radiation distribution the discharge has been observed and periods of time are found during which the discharge conditions are quasistationary. Electrical measurements yield the electrode drop voltages and the electric field strength as functions of pressure and current. A method for determining the discharge pressure from measurements of voltage drop across the lamp and current in closed discharge tubes is discussed. A calculation of temperature dependence of radiated power and electrical conductivity results in discharge temperatures of 10000–12000°K with an error of 10 … 15 percents.
