Intense heavy ion beams from the Gesellschaft für Schwerionenforschung (GSI, Darmstadt, Germany) accelerator facilities, together with two high energy laser systems: petawatt for experiments (PHELIX) and nanosecond (NHELIX) are a unique combination to facilitate pioneering beam-plasma interaction experiments, generate probe high-energy-density (HED) matter address basic physics issues associated driven inertial confinement fusion. In one class of will be used plasma beam study loss energetic...
The energy loss in a plasma target was measured for different heavy-ion species, ranging from $^{40}\mathrm{Ca}$ to $^{238}\mathrm{U}$ at an of 1.4 MeV/u. A discharge tube used generate hydrogen with high degree ionization and temperatures between 1 2 eV. An on-line diagnostic the performed measure free-electron density electron temperature. Compared neutral same particle density, shows enhanced stopping power due increased transfer free electrons, higher effective charge projectiles inside...
Experiments are presented which demonstrate, for the first time, extreme stopping power of fully ionized hydrogen plasma low-energy (45 keV/u) heavy ions.

Abstract The high-energy/high-intensity laser facility PHELIX of the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany, has been operation since 2008. Here, we review current system performance, which is result continuous development and further improvement. Through its versatile frontend architecture, can be operated both long- short-pulse modes, corresponding to ns-pulses with up 1 kJ pulse energy sub-ps, 200 J pulses, respectively. In mode, excellent temporal contrast...
We present in situ measurements of spectrally resolved X-ray scattering and diffraction from monocrystalline diamond samples heated with an intense pulse heavy ions.
