The Office of Science of the
Department of Energy is currently planning to proceed with the
construction of an advanced radioactive beam facility in the
U.S. This facility will have unique capabilities compared with
others both existing and planned elsewhere. The Facility for
Radioactive Ion Beams (FRIB) would consist of a heavy-ion driver
linac, a post-accelerator and experimental areas. Secondary
beams of rare isotopes will be available as high quality
reaccelerated or stopped beams from a gas catcher and high power
ISOL targets, as well as, high energy beams following in-flight
fragmentation or fission of heavy ions. The proposed design of
the FRIB driver linac is a CW, fully superconducting, 833 MV
linac capable of accelerating uranium ions up to 200 MeV/u and
protons to 580 MeV with 400 kW beam power. The subject of the
talk is results of an extensive research and development
effort which has resolved many technical issues related to the
construction of the driver linac and other systems required for FRIB.
