This material is based upon work supported by the James N. Boelkins Natural and Applied Sciences Division Research Award and the Hope College Department of Chemistry.
The Facility for Rare Isotope Beams (FRIB) will be a new national user facility,
funded by the Department of Energy Office of Science (DOE-SC) Office of Nuclear
Physics and operated by Michigan State University (MSU). The new facility will
have the capability to accelerate uranium to 200 MeV/nucleon and lighter ions
with even more energy. FRIB will generate a host of new isotopes that could
be harvested for off-line use. A feasibility study to harvest useful long-lived
radioisotopes from FRIB is being conducted. The study will use current conditions
at the National Superconducting Cyclotron Lab (NSCL) to quantify and characterize
the production and extraction yields of six important radioisotopes. The relatively
long-lived isotopes are 22Na, 67Cu, 48V, 85Kr, 44Ti, and 32Si. The radioisotopes
of interest will be collected in an aqueous beam stop. Modeling of the nuclear
reactions present at the NSCL was done using the LISE++ program. The information
from the modeled reactions is being used to create an efficient procedure for
isolating and extracting the radioisotopes of interest from the aqueous beam
dump at FRIB. The isolation and extraction procedure is first being developed
using commercial chelation disks for “cold,” non-radioactive, species.
The procedure will then be applied to “hot,” radioactive, species,
before being implemented at the NSCL and, eventually FRIB.
