The plot below shows the "year-one" rates for FRIB beams based on primary beam intensities of  10 kW. The thin black line on the neutron-rich side is the approximate boundary of known nuclei. The red squares are the primary beams produced by FRIB. These are fragmented to produce the other nuclei shown at the rates indicated on the right-hand side. The nuclei of interest for a given experiment are selected by the fragment separator. The rate for each nucleus can be obtained here https://groups.nscl.msu.edu/frib/rates/fribrates.html The beam intensities will be continually increased, with estimated intensities in the coming years of 20 kW (2025), 50 kW (2026), 100 kW (2027) and 400 kW (2029).
