The NUSTAR/HISPEC slowed down beam project[1] at GSI/FAIR is dedicated to rare isotopes with energies of upto 10 MeV/u. These radioactive beams will be used for spectroscopy and reactions studies. The setup for slowing down will utilize a thick degrader positioned after the FRS/Super-FRS separators at GSI/FAIR, followed by transmission detectors for energy and trajectory reconstruction. As a test, Coulomb excitation of a slowed down 64Ni beam on a gold target was performed in Sep-Oct 2008 at GSI. TPC and MCP detectors were used for the tracking of the beam before and after slowing it down. The gold target, placed after the tracking setup, was surrounded partially with two DSSSDs and NaI γ-detectors. The results from the test experiment and a comparison to simulations will be presented.
