FRIB Single Event Effects Facility

The FRIB Single Event Effects (FSEE) Facility was established by the U.S. Department of Defense and provides U.S.-based users with heavy ion beams, accurate characterization of beam parameters and linear energy transfers (LETs), easy-to-use controls, and prompt reporting of dosimetry results. Utilizing FRIB's state-of-the-art linear accelerator, the FSEE Facility lets users fulfill an extensive range of experimental needs.

Below is the current beam list and ion cocktails offered by the FSEE Facility. Additional ion species and cocktails are also in development at this time.

The FSEE Facility has a dedicated beamline built on the FRIB linac infrastructure. A user experimental station is established at the end of the FSEE beamline. A thin vacuum window defines the exposure area of the beam (1-inch diameter). A 4-degree-of-freedom stage allows for samples to be mounted and accurately positioned. A user control room is located nearby which houses robust industrial software controls, control for device presentation to the beam, and real-time monitoring of dose statistics.
