In this study, x-rays emitted from Ne-like and F-like copper plasmas have been modeled by modifying the original atomic and hydrodynamic EHYBRID code. X-ray resonance lines between 8 Å and 13 Å, and X-ray intensities from free-free and free-bound emission with the Si-, Al-, Mg-, Na-, Ne- and F-like ions emitted from copper plasmas created by KrF laser pulses have been modeled using single pulse configurations. Laser energy to x-ray energy conversion efficiencies have been calculated. For example; 0.195 % x-ray conversion efficiency is calculated from copper plasma created using a 249 nm, 25 ns pulse duration KrF laser pulse focused to W/cm2 in good agreement with published experimental measurements. For example, x-ray energy conversion efficiency for W/cm2 and 18 ns pulse duration is calculated as 1.29 % over 2 sr.
