The reaccelerator ReA is a state-of-the-art super-conducting linac for reaccelerating rare isotope beams produced via inflight fragmentation or fission and subse-quent beam stopping. ReA was subject of an upgrade that increased its final beam energy from 3 MeV/u to 6 MeV/u for ions with charge over mass equal to 1/4. The upgrade included a new room-temperature rebuncher after the first section of acceleration, a new β = 0.085 QWR cryomodule and two new beamlines in a new ex-perimental vault. During commissioning, beams were accelerated with near 100 percent transport efficiency through the linac and delivered through beam transport lines. Measured beam characteristics match those calcu-lated. Following commissioning, stable and long living rare isotope beams from a Batch Mode Ion Source (BMIS) were accelerated and delivered to experiments. This con-tribution will briefly describe the upgrade, and results from beam commissioning and beam delivery for experi-ments.

The Facility for Rare Isotope Beams (FRIB) project has completed technical construction in January 2022, five months ahead of schedule baselined about 10 years ago. Beam commissioning has been planned in seven phases starting from 2017 when the normal-conducting ion source and RFQ were commissioned. In April 2021, FRIB driver linac commissioning was completed with heavy ion beams being accelerated to energies above 200 MeV/u using 324 superconducting radiofrequency (SRF) resonators contained in 46 cryomodules. In preparation for high-power operations, a liquid lithium charge strip-per was used to strip uranium beam from average charge state of 33+ to 78+, and multiple charge states were accelerated simultaneously in the linac. By January 2022, FRIB target and fragment separator commissioning was completed with rare-isotope beams produced and identified. In May 2022, the first FRIB user scientific experiment was successfully conducted. This talk summarizes the FRIB accelerator project commissioning and early operations experience with discussions on strategic planning, operational envelope conformance, technical risk mitigation, and lessons learned.
