With an average beam power two orders of magnitude higher than operating heavy-ion facilities, the Facility for Rare Isotope Beams (FRIB) stands at the power frontier of the accelerator family. This report summarizes the status of design, technology development, construction, commissioning, as well as path to operations and upgrades. We also highlight beam instrumentation challenges including machine protection of high-power heavy-ion beams and complications of multi-charge-state and multi-ion-species accelerations.

During slip stacking in the Recycler, up to six batches of 84 bunches each are slipped by each other to and then captured to double the intensity of the the extracted beam. For nominal chromaticity settings, a bunch by bunch transverse damper system is needed to maintain beam stability but this system is blind to the bunches as they are slipping. The initial solution was to drastically raise the chromaticity to keep the beam stable. A new frequency based damper using diode detectors was developed to provide damping during slip stacking and allow the chromaticity to be reduced to nominal settings.
