Inelastic X-ray Scattering at NSLS-II

February 7- 8, 2008
 

Purpose

To develop the scientific and technical case for a beamline at NSLS-II designed to supply an exceptionally bright and intense source of hard x-rays for inelastic x-ray scattering (IXS) experiments with extremely high resolution of 0.1meV. It is anticipated that a Beamline Advisory Team (BAT) will form as a result of the discussions at this workshop and that this BAT will submit a Letter of Interest to work with NSLS-II on the design, construction and commissioning of this beamline. 

Syllabus

This beamline aims to develop advanced instrumentation that will enable IXS experiments with extremely high resolution of 0.1meV at energies close to 9keV where NSLS-II will deliver exceptional performance with flux over 1015 photons per second per 0.1% bandwidth. This will involve novel optical schemes that are beyond state-of-the-art and will move the highly successful IXS technique into a new and unmatched regime.

The beamline should be immediately useful for investigating crossover behaviors between continuum and short wavelength dynamics in disordered materials, and is expected to find other applications in areas such as the relaxation processes in soft matter, phonons in single crystals, surfaces, thin films, materials under extreme conditions, and exotic excitations in strongly correlated materials.

This workshop will explore the new scientific opportunities that this beamline will provide. Instrumentation needed for pursuing these opportunities will also be discussed. In addition, this workshop will also address future needs of the IXS community at NSLS-II, beyond the initial project beamline.
