The time-dependent Kr2F* fluorescence and KrF* laser emission of an electron beam pumped KrF laser are measured for two gas mixtures, 89.7% Ar/10% Kr/0.27% F2 and 99.6% Kr/0.4% F2, at initial gas temperatures from 294 to 417 K and for pulse lengths >600 ns. The measurements indicate an inverse square root temperature dependence for the Kr2F* formation, which is weaker than earlier predictions. Analysis of the Kr2F* and KrF* data also indicates that electron quenching and the effects of gas heating during the pump pulse significantly affect the laser performance of the Kr/F2 mixture. Results of a model agree well with the data.

The spatial distribution and absolute values of the stopping power of the rare gases Kr, Ar, and Ne were determined in 250-kV electron beam excited gas mixtures. The measured values were compared with 1D and 3D Monte Carlo code calculations. Excellent agreement was found in alI cases.
