High energy density in solid rare gas targets and solid hydrogen

The accelerator facilities at GSI Darmstadt offer a unique possibility for experiments with heavy ion induced dense plasma. Although the intensity of these heavy ion beams is far below the regime of Inertial Fusion Energy (IFE), such beams are used to study basic physics and to develop diagnostic tools and special heavy ion target designs. During the last years hydrodynamic motion has been induced for the first time in cryogenic crystals and metal targets by stopping intense heavy ion beams. In recent experiments at the High Density Target Area a maximum specific energy deposition of 1 kJ/g in the target was reached. The next generation of targets will consist of rare gas crystals of neon and hydrogen and compound targets, where the high energy deposition of high Z materials is combined with the observation of the interesting phenomena in rare gases or hydrogen. A first step is taken with the implementation of a new cryosystem and first experiments with solid neon as target.
