Abstract

The Holifield Radioactive Ion Beam Facility (HRIBF) is a national user facility dedicated to nuclear structure and astrophysics research with Radioactive Ion Beams (RIBs) using the Isotope Separator On-Line (ISOL) technique. HRIBF also maintains a vibrant development program for ISOL targets, ion sources and diagnostics. As a bridge to RIA, HRIBF continues to expand its technology. Presently, a $4.75M High Power Target Laboratory (HPTL) is being constructed to provide a facility for testing new targets, target geometries, ion sources and beam preparation techniques. HPTL will ultimately be co-located with a second RIB production system (IRIS2). An external axial injection system for the driver cyclotron, ORIC, is planned to provide higher beam intensities, reduce machine activation and eliminate cathode lifetime limitations. A multi-channel residual gas BPM is under development for measuring intensity and position of the driver beam. RIB production via electron-induced photofission is also being explored to attain higher intensities.
