ABSTRACT

  This beamline is dedicated to the study of the dynamics of materials using inelastic X-ray scattering (IXS) [Baron, et al, J. of Phys. Chem. Solids 61, (2000) 461]. IXS measures the dynamic structure factor, S (Q, ω), with ∼ meV energy resolution and > 1nm-1 momentum transfers. This is particularly interesting for disordered materials and small samples, where neutron scattering has severe limitations. In particular, IXS allows access to ∼ 1 nm-1 momentum transfers and large (< 0.5 eV) energy transfers with ∼ meV resolution - a region inaccessible for most neutron spectrometers and of great interest for liquids and glasses (disordered materials). Meanwhile the beam size, ∼ 100 µm diameter, makes small samples (< 0.01 mm3) readily accessible, a vast improvement over the ∼ 100 mm3 typically needed for neutron scattering.
