Modeling of bright Fe K-shell emission from laser-irradiated targets and comparison to data

We used the ``high-flux'' model incorporated in a 2D radiation-hydrodynamics code to simulate the Fe K-shell emission from under-dense Fe plasmas created by laser-driven targets on both the Omega laser at the University of Rochester and the National Ignition Facility laser at LLNL. In the high-flux model, independently developed by Colvin et al. (Phys. Plasmas 17, 073111, 2010) and Rosen et al. (HEDP 7, 180, 2011), non-local electron thermal conduction is modeled in the Spitzer-Harm formulation with a large flux limiter, and ionization levels are computed in non-LTE with a Detailed Configuration Accounting atomic model specially constructed for the Fe K-shell. In this presentation we show the simulated emitted x-ray power vs time in several x-ray photon energy bands and the time-integrated emitted spectra, and compare these simulated results to the corresponding data from several actual Omega and NIF shots.
