Abstract
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:

a- 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.

b- 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.

c- 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.

d- 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.
