A commercial finite-element analysis code is used to calculate axisymmetric transient temperature fields, current density distributions and energy fluxes in the cathode of a high-intensity discharge lamp powered by a unipolar current I(t). The calcul

The axisymmetric energy fluxes in an arc cathode are calculated by a commercial finite-element analysis code. The model decouples the sheath from the arc. Exclusively a spot mode exists at small integral loads by heat flux in the steady state for a c

A method is presented for determining & f ;-values and the resonance interaction constant K of resonance lines from absorption measurements. The total absorption of two Kr I and five Xe I resonance lines between 1140 A and 1500 A has been measured as

The large electric fields in the cathode sheath of high pressure glow discharges lead to localized energy deposition in the gas, which drives a gas dynamic pressure wave into the region where the transient high pressure glow is homogeneous. For a ran

A self‐consistent two‐dimensional (2D) model of large volume inhomogeneously preionized transient high‐pressure glows as used in XeCl lasers is described. The basic concept is to use a curvilinear orthogonal coordinate system generated by confo

A near-infrared, interferometric measurement of the density distribution of the electrons and excited xenon atoms has been performed at two discharge pumped, X-ray preionized XeCl lasers. The experimental results of one of these lasers are in good ag
