title: Atomic physics modeling of transmission spectra of Sc-doped aerogel foams to support OMEGA experiments.
abstract: 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 (ScSi6O12at 75 mg/cm3density). We have determined that in the 50-200 eV Terange there is a significant difference in the 1s-3p spectra, especially below 100 eV, and for Te= 200 eV above 5000 eV in photon energy. Examining synthetic spectra generated using OPLIB with 300 resolving power reveals spectral sensitivity to Techanges of ∼3 eV.
