Typical efficiencies, however, for the charge-state conversion of very heavy ions are about 15-30% with common charge strippers. Actually, the total efficiency of two charge strippers for the uranium acceleration at the RIBF is only 6%. The low conversion efficiency is an important bottleneck for the intensity upgrade. Multi-charge acceleration proposed in the FRIB project is a unique method for linac to drastically increase the low conversion efficiency. The method, unfortunately, is not applicable for the ring accelerators such as cyclotrons. In the present study, we designed high-efficient charge stripper rings which have applicability to the cyclotron cascade using the technical knowledge of gas stripper recently developed at the RIBF.
