The Isotope Harvesting Program at FRIB Greg Severin and Chirag Vyas This material is based upon work supported by the U.S. Department of Energy s Isotope Program, Award# DE-SC0021193, DE-SC0021220, and Michigan State University. Michigan State University designed and established Isotope Harvesting Program at FRIB in support of the mission of the U.S. Department of Energy s Isotope Program.
FRIB is Located at Michigan State University, USA Facility for Rare Isotope Beams U.S. Department of Energy Office of Science | Michigan State University 640 South Shaw Lane East Lansing, MI 48824, USA frib.msu.edu Greg Severin INPC 2025
The Heart of FRIB is a Linear Heavy Ion Accelerator For example: The beam hits a thin target and creates fragmentation-product radionuclides inflight The fragmentation products are steered to experimental stations downstream 48Ca20+ is accelerated to > 200 MeV/nucleon, 1-50 A (up to 400kW) Facility for Rare Isotope Beams U.S. Department of Energy Office of Science | Michigan State University 640 South Shaw Lane East Lansing, MI 48824, USA frib.msu.edu Greg Severin INPC 2025

Key Points of the Isotope Harvesting Program Hot cells and piping were built to accommodate isotope harvesting while FRIB is operating at full power (400 kW primary beams) All installation is complete, and commissioning is underway The first isotopes to be harvested are 47Ca and 76Kr (simple chemistry, high production rates). We aim to provide isotopes to the research community, including by feeding back into FRIB accelerators (e.g. ReA6). Niche: ~2 neutrons from stability, ~day(s) half-life 56Ni, 140Ba, 28Mg, etc. Facility for Rare Isotope Beams U.S. Department of Energy Office of Science | Michigan State University 640 South Shaw Lane East Lansing, MI 48824, USA frib.msu.edu Greg Severin INPC 2025
