FRIB features
Unprecedented discovery potential
There are some 300 stable and 3,000 known unstable
(rare) isotopes. FRIB will produce and make available for
research these and many undiscovered rare isotopes.
FRIB will enable scientific research with fast, stopped,
and reaccelerated rare isotope beams, supporting a
community of about 1,500 scientists around the world
planning experiments at FRIB.
Supporting the mission of the Office of Nuclear Physics in
U.S. Department of Energy Office of Science (DOE-SC),
FRIB will enable scientists to make discoveries about
the properties of rare isotopes, nuclear astrophysics,
fundamental interactions, and applications for society,
including in medicine, homeland security, and industry.
FRIB history and status
In December 2008, the DOE-SC announced that MSU
had been selected to design and establish FRIB. At the
heart of FRIB is a high high-power superconducting
linear accelerator that already has been demonstrated
to accelerate ion beams to more than half the speed of
light to strike a target, creating rare isotopes. With these
beam tests demonstrated, FRIB became the highestenergy
superconducting heavy- ion linear accelerator.
Another significant milestone was achieved in September
2020, when FRIB was designated as DOE-SC’s newest
scientific user facility. FRIB adjoins and incorporates the
precedent NSCL facility making effective use of existing
infrastructure. In August 2021, the FRIB Program Advisory
Committee (PAC) peer-reviewed the first set of science
proposals for experiments that will be conducted after
FRIB commences user operation in 2022. The PACrecommended
experiments align with national science
priorities and span FRIB’s four science areas and technical
capabilities.
Funding and future impacts
FRIB is funded by the DOE-SC, MSU, and the State of
Michigan, with user facility operation supported by the DOE-
SC Office of Nuclear Physics. The DOE and the National
Science Foundation have invested over $1 billion to establish
FRIB. Three-quarters was invested in Michigan, and over
94% in the United States. FRIB has strong bi-partisan, bicameral
support from the federal government and a broad
base of research funding across several agencies.

• A superconducting-radio frequency
driver linear accelerator (linac) that
provides 400 kW for all beams with
uranium accelerated to 200 MeV per
nucleon and lighter ions to higher energy
(protons at 600 MeV per nucleon).
• Two electron cyclotron resonance (ECR)
ion sources 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
per nucleon for uranium and 1 GeV for
protons without significant interruption
of the future science program.
• An advanced fragment separator to
select rare isotopes
• Three rare isotope stopping stations
• Experimental areas (47,000 square
feet) for stopped beams, reaccelerated
beams, and fast beams.
• Upgrade options include doubling the
size of the experimental area, adding
a neutron-scattering facility, or the
addition of ISOL or light-ion injection.
• Pre-FRIB science program using the
existing in-flight separated beams
from ReA3 and ReA6 reaccelerators.
Users can be able to mount and test
equipment and techniques and do
science with the beams at all energies
in-situ so that they are immediately
ready for experiments when FRIB is
complete; this allows for a continually
evolving science program while FRIB is
being completed, seamlessly merging
into the FRIB research program.
• A User Relations Office to support
development of user programs.
