Description

Since starting scientific user operation in May 2022, the driver linac in The Facility for Rare Isotope Beams (FRIB) at Michigan State University has provided more than a dozen ion beam species from Oxygen to Uranium to the production target. FRIB has routinely provided 20 kW primary beams on target since March 2025, which is a factor of 20 higher than at the beginning of scientific user operation. This presentation reports on the beam loss observed in the recent operations, and also discuss the approaches for their mitigation.
