| description | The design of inertial confinement fusion (ICF) ignition targets requires radiation-hydrodynamics
simulations with accurate models of the fundamental material properties (i.e., equation of state,
opacity, and conductivity). Validation of these models are required via experimentation. A feasibility study of using spatially-integrated, spectrally-resolved, X-ray Thomson scattering (XRTS)
measurements to diagnose the temperature, density, and ionization of the compressed DT shell of a
cryogenic DT implosion at two-thirds convergence was conducted. Synthetic scattering spectra were
generated using 1-D implosion simulations from the LILAC code that were post processed with the
X-ray Scattering (XRS) model which is incorporated within SPECT3D. Analysis of two extreme
adiabat capsule conditions showed that the plasma conditions for both compressed DT shells could
be resolved. |
