Title:	Indirect heated plasma targets for heavy ion stopping experiments
Abstract:	The unique combination of a Petawatt High-Energy Laser System for Ion beam eXperiments ¿ ¿Phelix¿ (Nd:glass, 1053nm, 300-500 J,1-15ns) [1] and intense heavy ion beams of the UNILAC accelerator at GSI-Darmstadt allow creating and probing of hot plasmas with a density of some percentage of solid-state density. The experimental program aims at the investigation of fundamental features of heavy ion stopping in ionized matter in view of promising applications for the Heavy Ion Fusion and astrophysics [2, 3]. For combined experiments on the interaction of heavy ion beams with ionized matter (GSI) a high density plasma target with homogeneous in time (~ 5 ns) and space (~1mm) plasma parameters is required. For these purposes we are developing the combined target which consists on the Gold hohlraum (converter) and low Z foam target heated by the hohlraum radiation before probed by an ion bunch. Foam targets are rather promising due to the effective conversion of the deposited radiation energy into the internal plasma energy and slow hydrodynamic response on the heating. Direct irradiation of the Gold converter walls with a nanosecond pulse delivered by the PHELIX-laser system (GSI) leads to hohlraum radiation spectra in the photon energy range of 50-500 eV. Expected temperatures of the foam targets heated by this radiation amount to 20-30 eV at electron densities of 1021 cm-3. The results of the last hohlraum experiments carried out at PHELIX-laser energies of 200 -250 J will be presented.
