The ORNL project to produce medium-intensity, proton-rich, radioactive ion beams (RIBS) for astrophysics, nuclear physics, and applied research with the Holifield Heavy Ion Research Facility (HHIRF) accelerators has been approved. Radioactive atoms will be produced by fusion reactions in an Isotope Separator On-Line (ISOL)type target-ion source assembly using light ion beams from the Oak Ridge Isochronous Cyclotron (ORIC). The radioactive atoms will be converted to negative ions using either (1) direct-surface ionization or (2) charge exchange following positive ionization. After acceleration to approximately 300 keV from a high-voltage platform, these negative ions will be injected into the 25-MV tandem accelerator for acceleration to higher energies. Beams of up to mass 80 will be accelerated to energies greater than 5 MeV/nucleon. For some radioactive beams. intensities greater than I pnA are possible.
