Scientific reach of the ISF. Shown are the intensities after the fragment separator calculated for in-flight production and separation, based on the proposed fragment separator and assuming the availability of 200 MeV driver beams with 400 kW beam power for all stable elements. It should be noted that predictions for isotopes very far from stability represent extrapolations into the unknown and have, therefore, uncertainties that can be as large as one or two orders of magnitude.
