Abstract
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.
