University of Wisconsin
The University of Wisconsin Tandem Accelerator Ion
Beam is a 1.7 MV terminal voltage tandem ion accelerator (Model
5SDH-4, National Electrostatics Corporation Pelletron accelerator) featuring
dual ion sources for producing negative ions with a sputtering source or using
a radio frequency (RF) plasma source. This accelerator offers controlled
temperature proton irradiation capability with energies up to 3.4 MeV. The
analysis beamline is capable of elastic recoil detection and nuclear reaction
analysis. Transmission electron microscopy and scanning electron microscopy are
also offered at the University of Wisconsin. User Guide
University of Michigan
The 1.7 MV Tandetron accelerator in the Michigan
Ion Beam Laboratory at the University of Michigan offers controlled
temperature proton irradiation capabilities with energies up to 3.4 MeV as well
as heavy ion irradiation. Crack growth rate testing in controlled temperature,
pressure, and chemistry are also offered at the University of
Michigan. User Guide
The Intermediate Voltage Electron Microscopy
(IVEM)-Tandem Facility at Argonne National Laboratory combines ion
beam irradiation capability with in-situ characterization using a transmission
electron microscope. A total dose of 100 dpa can be achieved in about a day.
Capabilities include continuous recording to provide real-time observation of
defect formation and evolution during irradiation and well controlled
experimental conditions (constant specimen orientation and area, specimen
temperature, ion type, ion energy, dose rate, dose and applied strain). A
radiological facility, the Irradiated Materials Laboratory (IML), located in
the same building as the IVEM-Tandem, can receive, handle, prepare, and store
radioactive samples. User

The In-Situ Ion Irradiation Transmission Electron
Microscope (I3TEM) Facility at the Sandia Ion Beam Laboratory offers
ion irradiation, including in-situ irradiation in a transmission electron
microscope (TEM) with specialty specimen stages available, such as heating,
cooling, strain, compression, and changes in specimen environment. The I3TEM
Facility offers the capabilities of a 200 kV JEOL 2100 high-contrast TEM
combined with the implantation/irradiation capabilities of the 10 kV Colutron
and the 6 MV Tandem accelerators housed in the Sandia Ion Beam
Laboratory. User Guide
The Texas A&M
Accelerator Laboratory is one of the largest university ion

universal ion source); a 1 MV ionex tandetron accelerator (with a RF plasma
source and a SNICS source); a 1.7 MV ionex tandetron accelerator (with a RF
plasma source and a SNICS source); a high temperature vacuum furnace; a high
temperature gas furnace; a four-point-probe resistivity measurement; and
various heating and cooling systems for ion irradiations at different
temperatures. User Guide
Lawrence Livermore National Laboratory
LLNL's Center for Accelerator Mass Spectrometry (CAMS) hosts a 10-MV FN tandem Van de Graaff accelerator, a
NEC 1-MV tandem accelerator and a soon to be commissioned 250KV single stage
AMS deck to perform up to 25,000 AMS measurement per year, as well as a a NEC
1.7-MV tandem accelerator for ion beam analysis and microscopy. The research
and development made possible by accelerator mass spectrometry (AMS) and ion
beam analytical techniques is diverse and includes geochronology (for
archaeology, paleoclimatology, paleoseismology, and other disciplines); neotectonics;
geomorphology; ground water hydrogeology; carbon-cycle dynamics; oceanic and
atmospheric chemistry; bioavailability, and metabolism of chemicals, toxic
compounds, and nutrients; forensic reconstruction of Hiroshima and Chernobyl
dosimetry; detection of signatures of nuclear fuel reprocessing for
nonproliferation purposes; material analysis and modification studies; as well
as nuclear physics cross-section measurements and nuclear chemistry studies. Website
The Nuclear Science User Facilities (NSUF) is the U.S. Department of Energy Office of Nuclear Energy's only designated nuclear energy user facility. Through peer-reviewed proposal processes, the NSUF provides researchers access to neutron, ion, and gamma irradiations, post-irradiation examination and beamline capabilities at Idaho National Laboratory and a diverse mix of university, national laboratory and industry partner institutions.
