FRIB Single Event Effects facilities

FRIB’s facilities, including the FRIB Single Event Effects Facility (FSEE) and the K500 Chip Testing Facility (KSEE), are essential in addressing the national shortage of testing capacity for advanced microelectronics used in industries like spaceflight, wireless technology, and autonomous vehicles.

The FRIB SEE facilities, established with financial support from the federal government, provide U.S.-based users with heavy ion beams, accurate characterization of beam parameters and linear energy transfers, easy-to-use controls, and prompt reporting of dosimetry results.

FSEE is based on the FRIB superconducting linac, while KSEE is based on the K500 cyclotron. They provide similar beams and energies.
