Abstract
The work presented demonstrates a newly developed, rapid algorithm for the calculation of atomic scattering factors in the EUV for partially ionized plasmas. Using element specific input data, the code REFRAC, calculates plasma refractive index, atomic scattering factors and scattering cross sections with a runtime short enough to be used in-line with fluid codes to model ablative flow from a planar target. The algorithm demonstrates good agreement with data from the Centre for X-ray Optics (CXRO) at Lawrence Berkeley National Laboratory for carbon. This work aims to accurately model moderate irradiance (\(>10^{9}\)W cm\(^{-2}\)) EUV laser absorption within solid material and expanding plasma, to characterise the ablation properties and highlight the potential applications of such lasers.
