for the

unirib consortium
UNIRIB Consortium
  • The purpose is to provide a nuclear research facility at ORNL for consortium members
  • Consortium members:

EMIS 2007

Our Deliverable is Science – Nuclear Physics

  • We do research
  • We give scientific reports at meetings
  • We train students
  • UNIRIB, with ORISE and ORAU, provides a university atmosphere in a national laboratory

EMIS 2007

Motivation to build ORISS – Oak Ridge Isomer/Isobar Spectrometer and Separator:

  • Decay studies often possible from yield considerations, but limited by background from isobaric/isomeric contamination
  • Need high resolution separator for background suppression

ORISS predicted performance:

  • High mass resolving power, M/∆M up to 400,000 (FWHM)
  • Almost complete Suppression of neighboring isobar
  • High efficiency ~ 50%
  • Chemistry independent
  • Transportable
  • Cost effective
  • … use Multi-pass Time of Flight principle!

What you could do with mass resolving power of 400,000:

    • resolve all isobars
    • resolve isomers M/DM < 200,000 (470 kev @ A=100)
