We present here a summary of various and preliminary
experiments performed on the new facility LULI 2000. Four topics in the High
Density Energy Physics have been investigated:
Equation of State: we studied pre-compressed water, one of most abundant
component of Uranus and Neptune's mantle. We used a recent technique based
on generating a shock into a diamond anvil cell pre-compressed target. Some
new data on EOS surface in the range 2-3 Mbar have been obtained.
X-ray Thomson scattering: a strongly coupled and degenerated Aluminum plasma
has been produced and probed by Ti He-alpha radiation. By using a curved
spectrometer, the scattered spectrum has been measured a Compton shift from
electrons has been put in evidence.
Astrophysics in the laboratory: A radiative supercritical shock has been
produced into a gas cell filled with a low density of Xenon (0.1-0.3 bar).
Various diagnostics have been implemented to determine electron density
variation, precursor and shock velocities, the 2D shape of the shock at
different times and electron temperature.
Laser accelerated flyer: different flyer plate targets have been tested.
Typical shock loaded material was fused-quartz plate. Flyer velocities up to
55 km/s have been measured.© EDP Sciences 2006
