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.
Figure 1: Proposed layout of FRIB at MSU.
As listed on the FRIB website, features of the proposed facility include:
- Superconducting-RF 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
