Shared
Research Equipment
A cooperative
arrangement with the SHaRE User Facility and the HTML
User Center provides access to a wide variety of advanced
SEM, TEM,
and STEM instruments and expertise located on ORNL's main campus.
Advanced capabilities include atomic-resolution imaging,
high spatial resolution microanalysis (EDS and EELS), and electron holography
using TEM/STEM instruments; a Scanning Auger Microprobe for nanometer-scale
surface microanalysis and depth profiling; 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. These facilities are located outside of the
CNMS but may be requested in a CNMS proposal by attaching the one-page
SHaRE Appendix to provide additional details about your analysis
needs.
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.
