Preparing to Harvest Radioisotopes from FRIB
Dr. Graham Peaslee; Dr. Paul DeYoung
The Facility for Rare Isotope Beams (FRIB) will be a new national user facility at Michigan State University (MSU) and funded by the Department of Energy Office of Science Office of Nuclear Physics (DOE-SC). FRIB will have the ability to accelerate uranium to 200 MeV/nucleon and light ions with even more energy. A host of new isotopes will be generated by FRIB that could be harvested for off-line use. A study to harvest six of these useful radioisotopes from FRIB is being conducted. This study will use current conditions at the National Superconducting Cyclotron Laboratory (NSCL) to determine the production and extraction yields of six important radioisotopes. These six radioisotopes are 24Na, 67Cu, 48V, 85Kr, 44Ti, and 32Si, and will be collected in an aqueous beam dump at FRIB. Modeling of the nuclear reactions present at NSCL was done using two programs, LISE++ and Nucleonica. The information from these programs is being used to streamline the isolating and extracting procedures for the radioisotopes of interest from the aqueous beam dump at FRIB. These procedures are first being developed on “cold”, non-radioactive, species. These procedures will then be applied to “hot”, radioactive, species before being implemented at NSCL and, eventually, FRIB.
