Abstract

We present some preliminary results on the equation of state (EOS) of water in a pressure regime of astrophysical interest. In the: experiments, structured targets made of an aluminum step followed by a water layer are irradiated by the laser at an intensity up to 4 (.)10(14) W(.)cm(-2) to generate a shock wave. Velocities are measured in the two materials using a VISAR interferometric diagnostic for water, and a streak camera to measure target self-emission for Al. EOS points for water are obtained with the impedance mismatch method using Al EOS as a reference. Water reflectivity was also measured.

Abstract

The optical reflectance of a strong shock front in water increases continuously with pressure above 100 GPa and saturates at similar to45% reflectance above 250 GPa. This is the first evidence of electronic conduction in high pressure water. In addition, the water Hugoniot equation of state up to 790 GPa (7.9 Mbar) is determined from shock velocity measurements made by detecting the Doppler shift of reflected light. From a fit to the reflectance data we find that an electronic mobility gap similar to2.5 eV controls thermal activation of electronic carriers at pressures in the range of 100-150 GPa. This suggests that electronic conduction contributes significantly to the total conductivity along the Neptune isentrope above 150 GPa. (C) 2004 American Institute of Physics.

Abstract

We present equation of state points for iron, in the pressure range 10-45 Mbar, the first obtained with laser-driven shock waves. The experiment has been performed with the high energy laser Phebus, optically smoothed with Kinoform phase plates. Our results double the set of existing experimental data at very high pressures showing good agreement with the predictions of the quotidian equation of state model and with previous results.
