The availability of radioactive beams has opened new opportunities for the investigation of exotic drip-line nuclei. The NUSTAR/HISPEC slowed down beam project[1] at GSI/FAIR is dedicated to rare isotopes with energies of 10 MeV/u and less. These fragments will be used for spectroscopy and reactions studies at HISPEC. The slowed down setup will utilize a thick degrader positioned after the FRS/Super FRS separators at GSI/FAIR, followed by transmission detectors for energy and trajectory reconstruction. A feasibility study and a test experiment at the FRS were performed. In a follow up measurement at the UNILAC accelerator a 40 µ m silicon DSSD detectors equipped with fast preamplifiers were tested. These detectors are considered for fragment tracking at the future slow down beam setup. The results from the test experiments and comparison to the simulations will be presented.
