ID-D

The HPCAT 16ID-D beamline is dedicated to x-ray scattering and spectroscopy research of materials under high pressure, typically in diamond anvil cells (DAC). With beams of 2meV energy resolution at 57Fe energy of 14.413keV, nuclear resonant techniques are used for determining phonon density of state and Mössbauer effect for Fe-containing samples at high pressures. With beams of 1eV energy resolution, a high efficient instrument for x-ray inelastic scattering (x-ray Raman) provides information of charge dynamics and chemical bonding at high pressures. The 16ID-D station has also a setup of emission spectrometer, measuring the details of fluorescence signals for information of spin state and structures of valence electrons at high pressures.
