The Equation-of-State Dependence of Nonuniformity Growth in Cryogenic-DT Implosions on OMEGA

This work reports on the analysis of low-adiabat, cryogenic deuterium--tritium (DT), high-compression implosion experiments\footnote{ V. N. Goncharov \textit{et al}., Phys. Rev. Lett. \textbf{104}, 165001 (2010).} performed on OMEGA using 2-D \textit{DRACO} simulations.\footnote{ S. X. Hu\textit{ et al}., ``Two-Dimensional Simulations of the Neutron-Yield in Cryogenic-DT Implosions on OMEGA,'' submitted to Phys. Plasmas.} The growth of various target and laser perturbations has been investigated using 2-D radiation-hydrodynamic simulations with different fuel equation-of-states (EOS) such as the \textit{SESAME}-EOS, the Thomas--Fermi model, as well as the FPEOS table\footnote{ S. X. Hu\textit{ et al}., Phys. Rev. Lett. \textbf{104}, 235003 (2010).} recently created by the path-integral Monte Carlo method. It has been shown that uniform 1-D hydro simulations using the FPEOS table predicted $\sim $20{\%} lower neutron yield than the \textit{SESAME}-EOS case.$^{3}$ In this work, we will present the dependence of RT growth and neutron-yield reduction on these different equation of states from 2-D hydro simulations.
