Description
The RIKEN RI Beam Factory (RIBF) is working on the future upgrade project to increase the intensity of heavy ion beams, especially for the heaviest uranium beams which are particularly important in unstable nuclear physics research in the midst of global research competition. The charge conversion efficiency of the two charge strippers (He gas and rotating graphite sheet disk strippers) in accelerating the uranium beams at RIBF is only 5%, which is a serious bottleneck for the intensity upgrade.
We have proposed the use of a new device called Charge Stripper Rings (CSRs) as an effective way to dramatically increase charge conversion efficiency. The overall charge conversion efficiency will be increased to 50% (10 times of the current level) with the CSRs. The design and development status of CSRs will be discussed.
