X-Ray Thomson Scattering and Radiography from Spherical Implosions on the OMEGA Laser

X-ray Thomson scattering (XRTS) is an experimental technique that directly probes the physics of warm dense matter by measuring electron density, electron temperature, and ionization state [1]. XRTS in combination with x-ray radiography offers a unique ability to measure an absolute equation of state (EOS) from material under compression [1,2]. Recent experiments highlight uncertainties in EOS models and the predicted ionization of compressed matter, suggesting more validation of models is needed [3,4]. We present XRTS and x-ray radiography measurements taken at the OMEGA Laser Facility from directly-driven solid carbon spheres at densities on the order of 1x10$^{\mathrm{24}}$ g cm$^{\mathrm{-3}}$ and temperatures on the order of 30 eV. The results shed light on the equations of state of matter under compression. [1] S. H. Glenzer and R. Redmer. Rev. Mod. Phys. \textbf{81}, 1625 (2009). [2] A. L. Kritcher et al., J. Phys.
