X-ray spectral measurements and collisional radiative modeling of laser produced iron plasma

Spatially-resolved time-integrated X-ray spectra of laser produced iron plasma were recorded, in the spectral range from 10 to 12 Å. The newest version of the atomic code HULLAC was used alongside a radiation-hydrodynamics code to model the plasma and generate simulated spectra for comparison with the experimental one. The spectra were found to be characterized by line emission from Li-like Fe XXIV ions, with 2s-3p and 2p-3d dominant transitions. Ionization stage, electron temperature and density were inferred from spectroscopic measurements. Good agreement was found between the parameters obtained from the radiation-hydrodynamics code and the detailed atomic code.
