Radioactive ion beams at the HRIBF

The Holifield Radioactive Ion Beam Facility (HRIBF) is now delivering beams of radioactive ions for nuclear physics experiments. The radioactive ions are produced using the Isotope-Separator-On-Line (ISOL) technique and then injected into a 25 MV tandem electrostatic accelerator and accelerated to energies of 0.1-10 MeV per nucleon for light nuclei and up to 5 MeV per nucleon for nuclei heavier than 100 amu. In the past year, the facility has provided almost 1200 hours of 17F and 18F beams for research with intensities up to 3x106 ions/s on target. Also, the facility has provided beams of neutron-rich radioactive ions using proton-induced fission in a highly permeable uranium carbide target. The first such beam delivered to an experiment was 118Ag with intensities up to 2x106 ions/s on target. Details of the techniques used to produce these beams and other beam development projects will be discussed
