NUMERICAL-ANALYSIS ON TEMPERATURE-DEPENDENCE OF XECL-LASING CHARACTERISTICS

The recombination rate constants for Xe++Cl-+Ne-->XeCl+Ne and NeXe+ N eXe++Cl-+Ne-->XeCl+2Ne have been calculated in a temperature range of 100-400 K. At 7.34 X 10(19) cm3 of gas density, both rate constants o f the recombinations are found to increase to approximately 7.5 X 10(- 6) CM3/s at 120 K, a factor of approximately 4 higher than that at roo m temperature. The temperature dependence of XeCl-lasing characteristi cs has also been simulated by a steady-state kinetic-simulation code. The simulation has indicated not only the enhancement of the laser out put, but also the reduction of the halogen concentration in the lower temperature range.
