Abstract: | The emission characteristics of the low-pressure electrodischarge UV lamp based on a mixture of xenon with iodine vapors have been investigated. The lamp was pumped in a dc longitudinal flow discharge with an interelectrode spacing of 50 cm at an electric power of discharge of 50–250 W. We investigated the volt-ampere characteristics, the plasma radiation spectra, and the dependences of the radiation power and efficiency of the lamp on the discharge electric power and the partial pressure of xenon in the mixture. The total radiation power of the electrodischarge lamp in the 206– 350-nm range reaches 22 W at an efficiency of ≤11%.__________Translated from Zhurnal Prikladnoi Spektroskopii, Vol. 72, No. 2, pp. 247–250, March–April, 2005. |
