Department of Energy (DOE)-Oak Ridge National Laboratory (ORNL)

The Facility has served as a major national user facility by providing a wide variety of energetic heavy ions for performing research particularly in the areas of nuclear and atomic physics. These beams have been produced by means of two accelerators:
a 25 MV electrostatic accelerator, which is the largest of this type in the world, and the Oak Ridge Isochronous Cyclotron (ORIC), which serves as an energy booster for the tandem beams. HRIBF has a broad selection of major experimental apparatus which are available to users of the facility. These include:
UNISOR (UNiversity Ion Separator at Oak Ridge), an on-line mass separator in which neutron-deficient radioactive nuclei produced through heavy-ion-induced reactions are extracted for off-line investigations; a low-temperature facility (as low as 4 mK degrees) that can align the nuclei extracted from UNISOR; a spin spectrometer used for studying nuclear events with a high multiplicity of gamma-ray emissions; a close-packed array of 20 Compton suppressed germanium detectors for determining energies of gamma rays with high precision; a general-purpose scattering chamber; and a high resolution magnetic spectrometer, which includes a windowless gas target. Two more additional devices will be added before research is resumed in 1995:
a recoil mass spectrometer with capability to observe reactions products with high mass resolution at zero degrees relative to the direction of the beam and a device designed for nuclear astrophysics programs.
