Title: Atomic physics modeling of transmission spectra of Sc-doped aerogel foams to support OMEGA experiments

Here, we present synthetic transmission spectra generated with PrismSPECT utilizing both the ATBASE model and the Los Alamos opacity library (OPLIB) to evaluate whether an alternative choice in atomic data will impact modeling of experimental data from radiation transport experiments using Sc-doped aerogel foams (ScSi 6O 12 at 75 mg/cm 3 density). We have determined that in the 50-200 eV T e range there is a significant difference in the 1s-3p spectra, especially below 100 eV, and for T e = 200 eV above 5000 eV in photon energy. Examining synthetic spectra generated using OPLIB with 300 resolving power reveals spectral sensitivity to T e changes of ~3 eV.
