We calculate in-target production rates of radioactive nuclei in the case of single-stage spallation targets designed for EURISOL (European Isotope Separation On-Line Radioactive Ion Beam Facility). Using particle generation-transport codes, we estimate the isotopic distributions of the reaction products, in terms of their charge and mass numbers, for 320 configurations of cylindrical targets. For 11 elements of the highest priority (Li, Be, Ne, Mg, Ar, Ni, Ga, Kr, Sn, Hg, Fr) and 23 of their isotopes far from stability, this study helps in deciding which target configuration can be retained or discarded to reach the highest production rates. |
