The Scattering and Instrumentation Sciences team supports basic research activities in the core research areas: X-ray Scattering, Neutron Scattering, and Electron and Scanning Probe Microscopies. The team also supports the DOE EPSCoR program. This activity supports basic research at both
universities and DOE national laboratories in condensed matter physics and
materials physics using electron, neutron, and x-ray scattering
capabilities. Research includes experiment and theory that seeks
to achieve a fundamental understanding of the atomic, electronic, and
magnetic structures and excitations of materials as well as the
relationship of these structures and excitations to the physical
properties of materials. Also supported is the fundamental dynamics in
complex materials, correlated electron systems, nanostructures, and novel
systems using advanced ultrafast spectroscopy, diffraction and microscopy.
The emphasis is on using time-domain approaches to provide new
understanding of complex behavior, emergent phenomena, and exotic
properties in condensed matter. Another increasingly important part of the
portfolio is studying the nature of materials at the nanoscale including
ordering fluctuations, and the structure and composition of
inhomogeneities such as defects, interfaces, surfaces, and precipitates.
The continuing development and improvement of next-generation x-ray and
neutron scattering instrumentation including a full range of elastic,
inelastic, and imaging techniques as well as ancillary technologies such
as novel detectors, sample environment, data analysis, and technology for
producing polarized neutrons is also supported. Advancing the state of the
art of electron beam and scanning probe techniques and instrumentation for
quantitative microscopy and microanalysis is an essential element in this
portfolio. The increasing complexity of energy-relevant materials
currently of interest such as superconductors, semiconductors, and magnets
requires ever more sophisticated scattering techniques to extract useful
knowledge and to develop new theories for the behavior of these materials.
X-ray, neutron, and electron scattering are
the primary tools for characterizing the atomic, electronic, and
magnetic structures of these materials.
