User Facilities
FRIB collaborates with experts from national laboratories, universities, and industry to develop state-of-the-art scientific instruments that support its science mission.
FRIB is the premier rate-isotope beam facility, able to produce a majority (approximately 80 percent) of the isotopes predicted to exist. To realize the unprecedented discovery potential of FRIB, exquisite, state-of-the-art experimental instruments are needed. The instruments enable scientists to study these isotopes at the highest rates produced.
Some FRIB instruments are in use now and others are being developed. Learn more about current and future instruments below.
Below are the technical specifications and capabilities of the scientific instrumentation used to conduct experiments on the rare isotope beams created at FRIB. Also included (when applicable) are links to the dedicated groups for the instruments. For laboratory-supported instruments, links are also provided to the service-level and responsibilities descriptions.
A service level description is available for ReA users that describes the level of support available for experiments in the ReA3 and ReA6 experimental areas.
It is possible to use a number of auxiliary instruments on the general purpose beamlines and at the secondary target position of the S800. Collaboration is required for use of auxiliary instruments not supported by the laboratory. The contact person listed for each instrument must be involved in the preparation of any proposal.
The data acquisition system is documented here. This site includes tutorial and reference documentation. A service level description is available that describes the level of service FRIB provides for Scientific Data Acquisition for user experiments.
A service level description is available for the Data-U area, outlining the support provided for experiments in the user data center environment.
The instruments enable scientists to study isotopes at the highest rates produced. Visit each instrument for service-level and responsibilities descriptions.
