It is expected that the upgrade of the heavy ion synchrotron (SIS) at the GSI Darmstadt will allow acceleration of U+28 ions to energies of about 200 MeV/u by the end of 1999. Employing a multi-turn injection scheme, the total number of particles in the beam could be as high as 2x1011 and use of a powerful rf-buncher would compress the pulse to a duration of about 50 ns.
The above beam parameters lead to a specific power deposition of 1-2 TW/g in solid matter, that will create solid density plasmas at temperatures of the order of 10 eV. This temperature regime is dominated by hydrodynamic related phenomena and is suitable for investigation of the equation-of-state properties of matter under extreme conditions. This paper shows with the help of numerical simulations that one can design heavy-ion-matter experiments at the SIS facility to study these effects including measurement of speed of sound and propagation of shock waves in solid targets.
