TI - FRIB from Commissioning to Operation J2 - Proc. of HB2023, Geneva, Switzerland, 09-13 October 2023 CY - Geneva, Switzerland T2 - ICFA Advanced Beam Dynamics Workshop on High-Intensity and High-Brightness Hadron Beams T3 - 68 LA - english AB - The Facility for Rare Isotope Beams (FRIB) was fully commissioned in early 2022, and the operation for physics experiments started shortly thereafter. Various ion beam species have been accelerated up to 240 MeV/u and delivered to the target. During the first year of user operations, the FRIB provided 4252 beam hours with 91\% availability for nuclear science. In addition, FRIB delivered about 1000 hours of various ion beam species at beam energies up to 40 MeV/u for single-event experiments. Typically, the experiments with a specific species rare isotope beam last a week or two. Each experiment requires a different primary beam species with specific energies. The primary beam power has been gradually increased from 1 kW to 10 kW over the past 1.5 years. The Accelerator Physics (AP) group develops high-level physics applications to minimize machine set-up time. Focuses include identifying beam halo sources, controlling emittances of multiple-charge-state beams, and studying the beam loss mechanisms to prepare for the ultimate 400 kW operation. This paper discusses the experience and challenges of operating a high-power CW heavy ion accelerator.
