Equation-of-state measurements for polystyrene at multi-TPa pressures in laser direct-drive experiments

Equation-of-state (EOS) measurements for polystyrene in TPa (10Mbar) pressure regions are presented. Polystyrene Hugoniot data were obtained up to 2.7TPa using impedance matching techniques with laser direct drive at the GEKKO/HIPER laser facility [N. Miyanaga et al., in Proceedings of the 18th International Conference on Fusion Energy (IAEA, Sorrento, Italy, 2001), IAEA-CN-77] The results were compared with theoretical models and previous experimental data and found to be in good agreement with the previous data obtained by different drive and diagnostic techniques.
