Gas stopping of rare isotope beams together with reacceleration is unique at the Facility for Rare Isotope Beams (FRIB) at the Michigan State University. The stopping techniques, with beam manipulation at very low energies, are important developments aimed to slow down fast beams for either use in stopped beam experimental devices or to be injected in the reaccelerator for experiments at...
A new helium gas catcher has been developed at the SLOWRI facility at RIKEN/RIBF aiming at the efficient conversion of the high-energy exotic RI beams from the BigRIPS separator to slow RI beams. The RI beams of relativistic energies are caught and thermalized in a cryogenic helium-gas filled chamber, and the thermalized ions are extracted by an RF ion guide system. The gas catcher has been...
