The interaction processes of heavy ions and ionized matter have been investigated extensivly during the last years. The plasmaphysics-group at GSI-Dmstadt has contributed to this research in several fields. At low ion energies (E = 45 keV/u) it was possible to create a heavy-ion heated plasmas with a high current radio-frequency-quadrupol (RFQ) accelerator. The interaction of this low energy beam with extemal generated hydrogen plasmas (ne = 1017 cmm3) showed an increased stopping by a factor of 35 in the plasma compared to a cold gas.In the medium energy range ( 1.5 MeVh < E < 10 Mevh) it was possible to see the effects of the enhanced stopping power of plasma ( 1017 cm-3 < ne < 1019 cm-3) due to the presence of free electrons. Furthermore the effect of the plasma to the ionisation-recombination balance of the heavy ions traversing the plasma was investigated. In the high energy range ( E > 100 MeV/u) the first hydrodynamic motion of heavy ion heated rare gas crystals has been observed recently. The aquisition of a high power Nd:Glass laser (E -100 J, t = 20 ns) makes it now possible to extend the density range of the extemally generated plasmas far beyound ne = 1019 cm-3. An overview of the recent experiments will be given and the impact of laser-produced plasmas in the framework of the progam investigating the interaction of heavy ions with ionized matter will be discussed. 3FP06Experiments on a laser-produced plasma cross-field motion f o r simulation of i n t e r a c t i o n between CRRES releases and geoplasma.
