The Facility for Rare Isotope Beams (FRIB) will be a world-leading, DOE Office of Science national user facility for the study of nuclear structure, reactions, and astrophysics on the campus of Michigan State University (MSU). A superconducting driver linac will be used to provide stable heavy-ion beams of >200 MeV/u at beam powers up to 400 kW to a production target. The stable beams will be used to produce rare isotopes by in flight fragment separation. The MSU-led design and construction effort is supported by collaborations with many National Laboratories and other scientific institutions. Systems Engineering and Integration has been implemented at the outset to ensure that a requirements-driven design process is followed, and to ensure intra and inter-system compatibility. Top-level requirements have been allocated, and subsequently elaborated, between the Accelerator Systems, Experimental Systems, and Conventional Facilities. FRIB has developed a number of methods and tools to track requirements, establish interfaces, monitor design progress, and ensure overall system integration. These will be described in the paper.

This paper will summarize the systems engineering techniques utilized to translate the FRIB accelerator physics lattice file to actual three dimensional CAD geometry for linac components. An automated approach of using the accelerator physics lattice database used for optics and particle simulation has been implemented to generate data points used to position the technical 3-dimensional CAD geometry. This coordinated method ensures consistency between the technical and scientific design domains throughout the project design phases. The FRIB configuration management used to control lattice and CAD model revisions is also discussed. In addition, the paper discusses fiducialization plans and tolerance stack up analysis to meet positional requirements for FRIB cryomodules, diagnostics, and the beam delivery magnet systems.

The FRIB Front End will provide beams of stable ions with a mass up to uranium at a beam energy of 500 keV/u and intensity required to achieve a power of 400 kW on the fragmentation target. In this paper, we describe progress with the design and construction of the Front End and its systems.

The Facility for Rare Isotope Beams (FRIB) is based on a continuous-wave superconducting heavy ion linac to accelerate all the stable isotopes to above 200 MeV/u with a beam power of up to 400 kW. At an average beam power approximately two-to-three orders-of-magnitude higher than those of operating heavy-ion facilities, FRIB stands at the power frontier of the accelerator family - the first time for heavy-ion accelerators. To realize this innovative performance, superconducting RF cavities are used starting at the very low energy of 500 keV/u, and beams with multiple charge states are accelerated simultaneously. Many technological challenges specific for this linac have been tackled by the FRIB team and collaborators. Furthermore, the distinct differences from the other types of linacs at the power front must be clearly understood to make the FRIB successful. This report summarizes the technical progress made in the past years to meet these challenges.
