ABSTRACT

  This beamline is dedicated to the study of the dynamics of materials using inelastic X-ray scattering (IXS) and nuclear resonant scattering (NRS) [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. NRS allows access to element specific densities phonon of states on the meV level, and several other techniques for probing dynamics (NFS, NBS, TDI) at the neV level.
