“…Several types 2020 JINST 15 P12034 of superconducting (SC) cavities operating at different frequencies were thoroughly investigated. We concluded that a 5-cell 644 MHz cavity with 𝛽 opt = 0.65 is the optimal option for the energy upgrade for the following reasons [48]:…”

A: The Facility for Rare Isotope Beams (FRIB) will be the world's premier rare-isotope beam facility. Experiments with the majority (∼ 80%) of the isotope predicted to exist will become available. The FRIB facility is based on a superconducting (SC) heavy ion linac with output energy above 200 MeV/u for any ions at beam power of 400 kW. FRIB includes a target facility for in-flight production of rare isotopes. A three-stage fragment separator will be used to prepare fast rare isotope beams with high-purity for nuclear physics experiments. The installation work of the accelerator and experimental systems is approaching completion and multi-stage beam commissioning activities started in summer 2017 with expected project completion in early 2022. The commencement of operation for users' experiments is planned immediately following the project completion.
