Ion Beam Materials Laboratory

The Ion Beam Materials Laboratory (IBML) on the University of Tennessee (UT) campus is a research partnership between UT and Oak Ridge National Laboratory (ORNL) that provides unique new capabilities that are available to the UT and ORNL scientific community, as well as other research and development organizations.

The IBML is equipped with a 3MV tandem accelerator, two ion sources, three beamlines, and four endstations that provide state-of-the-art capabilities for ion beam analysis, materials modification, fundamental research on ion-solid interactions, and applied research on radiation effects in materials for nuclear and space applications. This facility is committed to the university's mission of research and teaching, so the instruments are available for qualified faculty, students, and staff.

Qualified users may reserve instrument time through the IBML facility manager. The capabilities of the IBML are also available as a research service.

The IBML staff examines instrumentation on the ion-beam endstations.

Ion beam analysis (IBA) can be used to obtain elemental and isotopic composition profiles in the near-surface layer of materials. IBA methods can achieve elemental resolution in the parts per million range, and depth resolution is typically on the order of a few nanometers over depths to a few micrometers. IBA capabilities and service include:

  • Rutherford and non-Rutherford backscattering spectrometry
  • Ion channeling
  • Nuclear reaction analysis
  • Elastic recoil detection analysis
