Workshop 3

Scientific Advances in Inelastic X-Ray Scattering

Tue. May 6, all day

Organizers: Yuri Shvyd'ko, Diego Casa, Thomas Gog (all XSD APS)

To agenda > Updated 4/1/2008

One of the most significant scientific developments at third generation synchrotron sources in recent years is the emergence of Inelastic X-ray Scattering (IXS) as a mainstream experimental technique. IXS has been applied to the study of electronic and lattice excitations in condensed matter in such diverse disciplines as materials science, geoscience and biophysics. Subjects of investigation span "fancy" excitations in high-Tc superconductors, the propagation of phonons along DNA molecules and the time-evolution of electronic excitations on an attosecond time scale. As a reflection of these novel developments, a new dedicated IXS beamline has been commissioned at the APS to help meet the growing demands of a rapidly growing user community, which is accompanied by a steadily rising number of scientific publications in high impact journals. The workshop is designed to highlight recent advances in the science and applicable techniques in this exciting new field of synchrotron radiation research and to stimulate discussion of future perspectives and opportunities.
