  RIKEN RI Beam Factory (RIBF), providing the world’s most intense heavy-ion beams more than 345 AMeV, is a leading facility for generating in-flight RI beams. RIBF has been steadily developing its performance after since 2006. In particular, the beam intensity of uranium beams, which is important to produce in-flight fission RI beams, was drastically increased by a factor of 240 compared to 2008. For further intensity upgrade of the uranium beams, the total charge stripping efficiency less than 5% of two strippers, He gas and rotating graphite sheet disk strippers, is a serious bottleneck. A new acceleration scheme with charge stripper rings (CSRs) as a cost-effective way to enhance the charge stripping efficiency has been proposed. The CSR recycles beams other than the selected charge state that was previously dumped. These beams are orbited in the CSR while suppressing emittance growth, and then re-enter the stripper. The CSR is being studied as a future plan, aiming at a 10-fold increase in the intensity of the uranium beams. The present status and the future plan with the CSR at RIBF will be presented.
