ABSTRACT
This beamline provides Inelastic X-ray Scattering (IXS) and Nuclear Resonant Scattering (NRS) measurements, utilizing hard X-ray of > 14 keV.
1) In the IXS hutches, dynamic structure factor, S (Q, ω), with ∼ meV energy resolution and > 1 nm-1 momentum transfers can be obtained using the IXS spectrometer [Baron, et al, J. of Phys. Chem. Solids 61, (2000) 461]. This method can be a powerful tool for investigating atomic dynamics of disordered materials (liquids and glasses) 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. Meanwhile the beam size, < ∼100 µm diameter, makes small samples (< 0.01 mm3) readily accessible.
2) In the NRS hutches, the following methods are primally available; Atomic or molecular dynamics using nuclear resonant inelastic scattering in meV region (NRVS/NIS) and quasi-elastic scattering (TDI, Rayleigh Scattering) in neV-µeV region, Hyperfine/Mössbauer spectroscopy (NFS, EDMS). Mössbauer spectroscopy in Synchrotron facility is especially advantageous for measurements in extreme conditions, in diffraction condition, and in cases where no Mössbauer source is readily available. Focused beam is available up to the higher energies by the bend cylindrical mirror and the focused beam size is ∼ 50(H) µm×25(V) µm at 14.4 keV.
