Synopsis
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).

Technical details
The beamline permits inelastic x-ray scattering studies from collective ion excitations/phonons. MAIN BEAMLINE CHARACTERISTICS are as follows: Incident photon energy: 13840, 15817, 17794, 21747 and 23725 eV; energy resolution of 7.0, 5.5, 3.0 and 1.5 meV; energy transfer: 0-400 meV; focal spot size: 250 x 70μm2 or 14 x 10μm2; horizontal x vertical, FWHM; momentum resolution: typically 0.03 nm-1 (can be further improved by slits); momentum transfers from 1-100 nm-1; nine momentum transfers are recorded simultaneously. EXPERIMENTAL OBSERVABLES are the following: phonon dispersion, sound velocities, elastic constants, phonon density of states (and derived thermodynamic properties such as specific heat, entropy, Debye temperature and velociy, etc.)
