High energy heavy ions were generated in laser produced plasma at moderate laser energy, with a large focal spot size of 0.5 mm diameter. The laser beam was provided by the 10 GW GSI-NHELIX laser systems, and the ions were observed spectroscopically in status nascendi with high spatial and spectral resolution. Due to the focal geometry, plasma jet was(More)
This study deals with the simulation of the experimental study of Roth et al. ~2000! on the interaction of energetic Zn projectiles in partially ionized laser produced carbon targets, and with similar type experiments. Particular attention is paid to the specific contributions of the K and L shell target electrons to electron recombination in the energetic(More)
Experimental investigations of the slowing-down process of calcium projectile ions traveling through the neon gas were carried out at the UNILAC facility at GSI in the frame of the project U-189 " X-ray spectroscopy of projectile ion and target radiation ". The main goal was to demonstrate the influence of the target density on the charge state distribution(More)
A laser-driven, multi-MeV-range ion beamline has been installed at the GSI Helmholtz center for heavy ion research. The high-power laser PHELIX drives the very short (picosecond) ion acceleration on μm scale, with energies ranging up to 28.4 MeV for protons in a continuous spectrum. The necessary beam shaping behind the source is accomplished by applying(More)
PHELIX is a Petawatt high-energy laser for heavy-ion experiments that can deliver 1-10 ns long pulses at 1053 nm with energies up to 1 kJ to the ion beam target chamber at the Z6 experimental area or 200 TW in sub-picosecond pulses to the target chamber in the laser bay. Near-term upgrades comprise frequency doubling of the ns pulses to 527 nm and a power(More)
A large variety of fundamental issues in plasma and atomic physics can be ideally experimentally investigated by the combination of highly charged heavy-ion and powerful laser beams. The GSI is in the worldwide unique position to have both types of beams at its disposal, the two ion beams UNILAC and SIS-18 and the PHELIX (Petawatt High-Energy Laser for(More)
Concept The Z6 output sensor is the final PHELIX diagnostic prior to the target area Z6. During the first months of 2007 ray tracing calculations for the diagnostic system were done and the design was improved in efficiency. The pulse energy of a full system shot is up to 1 kJ with a maximum beam diameter of 280 mm. A test shot compared to a full system(More)
