Characteristics of a Glow Discharge in a Krypton/Elegas/Air Mixture

The longitudinal glow discharge in the Kr/SF₆/air mixture at a pressure of P = 0.7–6.0 kPa has been investigated. The electric characteristics and plasma radiation in the spectral region 150–340 nm are studied. The optimization of the radiation brightness (power) at = 249 nm in the KrF(B–X) mixture and in the nitrogen bands is carried out depending on the workingmedium composition and current magnitude. It is shown that a d.c. discharge in the Kr/SF₆/(N₂:O₂) mixture can be used in the multiwave UV–VUV radiation source on a system of the KrF and N₂ molecular bands.
