Non-LTE atomic physics model for laser fusion and X-ray laser simulation

In this report a method for calculating nonequilibrium atomic physics parameters in hot plasmas is described. This type of calculation is necessary for accurate simulation of laser fusion target experiments, where, generally, outside the ablation surface the target is non-LTE (Local Thermal Equilibrium). Another problem of interest in which non-LTE is important is in x-ray laser experiments. Here the whole process of interest depends on achieving a non-equilibrium atomic state, namely, a population inversion in selected atomic levels. The present model should provide a valuable calculational tool in support of several areas important to KMS programs.
