GENERAL
CHARACTERIZATION FACILITIES
- Advanced Electron Microscopy and Spectroscopy
A cooperative arrangement with the ShaRE User Program provides access to a
variety of advanced SEM, TEM, and STEM equipment and expertise located
on ORNL's main campus. Advanced capabilities include atomic resolution
imaging; a ‘bolometric’ X-ray detector for high performance microanalysis
at low beam energies; a Scanning Auger Microprobe for nanometer-scale surface
microanalysis and depth profiling; electron holography; a fully automated
electron microprobe for trace element determinations; and a variable pressure
SEM incorporating EDS and XRF analysis for the study of polymeric and nano-bio
samples. See Electron Microscopy, Neutron and
X-ray Scattering.
Note: ShaRE
and the High Temperature Materials Laboratory each operate their
own user program. Users needing only the capabilities of one of these
facilities and no other CNMS resources should apply directly to the
facility concerned. Such proposals will not be accepted in
the CNMS user program.
- Neutron Scattering
CNMS users are encouraged to take advantage of the world-class neutron scattering facilities that are available at ORNL’s High-Flux Isotope Reactor (HFIR) and the Spallation Neutron Source (SNS). Beamlines of particular relevance to CNMS Scientific Themes include the small-angle scattering and reflectometry instruments on the HFIR cold source, HFIR thermal neutron diffraction and spectroscopy capabilities, and early-availability instruments at SNS including the backscattering spectrometer and the liquids and magnetism reflectometers. CNMS users who may be interested in neutron scattering opportunities are encouraged to indicate their interest in the designated box on the CNMS proposal form. The CNMS will assist its users to identify the appropriate neutron scattering resources, develop competitive beamtime proposals, or collaborate with arrangements for potential access as initial users as additional instruments are commissioned.
