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.)
