【 摘 要 】

The scope of work for this subcontract requires that state-of-the-art, detailed atomic kinetics calculations be applied to compute the total radiative cooling rates for Ar and Kr in high density plasmas. This is in support of the Defense Threat Reduction Agency's program of development of simulators with high-fluence radiation and spectral fidelity. Using collisional-radiative modeling codes and unique expertise at Lawrence Livermore National Laboratory (LLNL), the total radiative yields from Ar and Kr, integrated over all photon energies, have been computed. Spectrally resolved yields from K-shell Ar and K- and L-shell Kr have also been tabulated. The present calculations show that high electron density in the plasma sources is essential to maximize the fraction of power output in various x-ray bands.
