FRIB Conceptual Overview

Rare isotope production with primary beams up to 400 kW, 200 MeV/u uranium

Fast, stopped and reaccelerated beam capability

ReA12 is outside scope of the project but MSU is building the building now, we hope to have this funded by NSF

Experimental areas and scientific instrumentation for fast, stopped and reaccelerated beams

What New Nuclides Will FRIB Produce?

• FRIB will produce more than 1000 NEW isotopes at useful rates (5000 available for study)

• Theory is key to making the right measurements

• Exciting prospects for study of nuclei along the drip line to mass 120 (compared to 24)

• Production of most of the key nuclei for astrophysical modeling

• Harvesting of unusual isotopes for a wide range of applications

Comments

• FRIB will open many opportunities in the study of atomic nuclei

– Nuclei along the drip lines

– Heavy r-process nuclei along N = 126

– Study of long isochains

• Theory is central to the success of FRIB

– We need theory to guide the program. What are the most sensitive measurements?

– We need reaction theory to interpret wave functions, occupancy, matter distributions, extract matrix elements, infer weak interaction strengths, etc.

• DOE and NSF must make a commensurate investment in theory - Now

• What do you need to make FRIB successful? The FRIB team an theory community must be committed to helping realize the needs.
