The implosion dynamics of an array of stainless steel (SS) wires on the Z and/or ZR accelerator produces an abundance of radiation from the K- and L-shell ionization stages. As the plasma assembles on axis, a number of time resolved snapshots provide temperature and density profiles and size of the emitting region. The non-LTE populations will be obtained by using detailed atomic models that include all important excitation, ionization, and recombination processes. In particular, we will investigate the effects of dielectronic recombination (DR) which is the most important recombination process for moderate to high Z plasma such as iron at moderate densities. We will analyze the ionization dynamics and generate K- and L-shell spectra using the temperature and density conditions generated in the Z and/or ZR accelerator describing the implosion with a 1-D non-LTE radiation hydrodynamics model.
