ID28 is dedicated to the study of phonon dispersion in condensed matter at momentum transfers, Q, and energy transfers, E, characteristic of collective atom motions. Main activities comprise the study of disordered systems and samples only available in very small quantities (<<1 mm^3v) and/or submitted to very high pressures (100 GPa and beyond).

Inelastic X-ray scattering (IXS) is therefore closely related to inelastic neutron scattering (INS) techniques, and consequently largely shares the scientific questions addressed in fields ranging from life science to materials research. IXS is particularly suited for the study of disordered systems such as liquids and glasses in a Q,E-range inaccessible to INS and of samples only available in very small quantities (<< 1 mm3) and/or submitted to very high pressures (up to 100 GPa).

Diffraction side station is available as supplementary instrument for the mapping of reciprocal space.
