The status of the msu re-accelerator (ReA3)

The Re-accelerator ReA3 [1] being developed at the Michigan State University is a major component of a novel system proposed to first stop the high energy Rare Isotope Beams (RIBs) created using Coupled Cyclotron Facility (CCF) by the in-flight particle fragmentation method in a helium filled gas system, then increase their charge state with an Electron Beam Ion Trap (EBIT) charge breeder, and finally re-accelerate them to 3 MeV/u to provide opportunities for an experimental program ranging from low-energy Coulomb excitation to transfer reaction studies of astrophysical reactions. The accelerator system consists of a Low Energy Beam Transport (LEBT) with an external multi-harmonic buncher, a radio frequency quadrupole (RFQ), a superconducting linac, and a High Energy Beam Transport (HEBT). The superconducting linac will use quarter-wave resonators with β_opt of 0.041 and 0.085 for acceleration and superconducting solenoid magnets for transverse focusing. The paper will discuss the recent progress of R&D and beam dynamics studies for ReA3.
