Abstract :
This paper describes a low-charge-state heavy-ion post-accelerator system for upgrading the Holifield Radioactive Ion Beam Facility. It is comprised of a room temperature 12.5-MHz RFQ, followed by a normal conducting IH linac, a SC IH linac and a SC QWR linac booster. The system is designed to accelerate ions with mass-to-charge ratio up to 140. The system can be used to accelerate beams directly (bypass the 25-MV tandem) or to post-accelerate beams from the tandem accelerator. By use of stripping between acceleration stages, low-charge-state radioactive ion beams of all elements, including uranium, can be accelerated to energies above the Coulomb barrier
