Experiments on the interaction of heavy ions with dense plasma at GSI-Darmstadt

摘要: Abstract One of the main objectives experimental plasma physics activities at Gesellschaft fur Schwerionenforschung (GSI) are interaction processes heavy ions with dense ionized matter. Gas-discharge targets were used for energy loss and charge state measurements in a regime electron density temperature up to 10 19 cm−3 20 eV, respectively. An improved model exchange fully hydrogen plasma, taking into account multiple excited electronic configurations which subsequently ionize, has removed discrepancies previous theoretical descriptions. The ion beam partially plasmas such as argon was found agree very well our simple based on modified Bethe–Bloch theory. A new setup 100 J /5 GW Nd–glass laser now provides access ranges 21 temperatures 100 eV. First results experiments laser-produced presented. To exploit possibilities laser-plasma both detection systems better diagnostics indispensable. Present developments future these fields This paper summarizes following contributions: • Interaction heavy-ion beams by C. Stockl et al. Energy Loss Heavy Ions M.
