Preferred Alternative Chosen for CD1 • Lowest cost configuration that meets technical requirements • Upgradable • Reviewed by ASAC, ESAC • Endorsed by mini-Lehman review March 17
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
Folded FRIB LINAC details • Physically compact layout • Minimize higher-cost subterranean structures • Single tunnel for all linac segments Grade (ground) level Tunnel Floor ~40 ft below grade
Preliminary Performance Baseline Schedule for 2018 Early Completion – CD-4 in 2020 CALENDAR YEAR TPC covers schedule range Paced by Funding Profile Paced by Facilities Paced by Installation & Test
FRIB Facility Upgrade Options Light Ion Injector ISOL Target Facility Symmetry tests SH elements Applications Multi-user operation 300 MeV/u (additional Cryomodules) Higher production rates
Nuclear Chart in 1966 The availability of rare isotopes over time Less than1000 Available today New territory to be explored with next-generation RIB facilities about 3000
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 Rates are available at http://groups.nscl.msu.edu/frib/rates/
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.
