FRIB at MSU
As proposed at MSU, FRIB will adjoin the existing NSCL facility and will offer measurements with fast, stopped, and reaccelerated beams of rare isotopes.

As listed on the FRIB website, features of the proposed facility include:
- Superconducting-RF folded driver linear accelerator that provides 400 kW for all beams with uranium accelerated to 200 MeV/nucleon and lighter ions with increasing energy (protons at 600 MeV/nucleon)
- Two ECR ion sources for redundancy with space to add a third ECR ion source
- Space in the linac tunnel and shielding in the production area to allow upgrading the driver linac energy to 400 MeV/u for uranium and 1 GeV for protons without significant interruption of the future science program
- Space to add multi-user capability
- One in-flight production target
- Space and infrastructure to add up to two ISOL targets or one additional in-flight production target with shielding to accommodate 1 GeV proton beams at 400 kW
- Three stopping stations -- two gas stopping stations and one solid stopper
- A superconducting-RF reaccelerator for reaccelerated beams up to 12 MeV/nucleon (uranium) and higher energies for lighter beams (e.g. 21 MeV/nucleon for 48Cr)
- Experimental areas (47,000 sq ft) for stopped beams, reaccelerated beams, and fast beams (Figure 2)
- Upgrade options include doubling the size of the experimental area or adding a neutron scattering facility
- Allowance for experimental equipment
