NSLS-II SEMINAR

The availability of synchrotron photons generated in high-flux and with energies greater than 60 keV has significantly advanced the field of materials research because of the great penetration and low absorption of high-energy x-rays. The ability of obtaining high angular resolution for high-energy x-ray scattering provides further research opportunities. Here I will present the development of a high-energy x-ray facility at the APS beamline 11IDC, where we combine a 2D detector and a high-resolution detection system for both rapid and high-resolution x-ray diffraction studies. A large variety of materials in bulk forms as well as in nano-scale phases can be investigated (using both diffraction and total scattering techniques) in confined and complex samples environments (e.g., in combination of temperature, pressure, stress, magnetic field). The technical details and scientific research opportunities at this beamline will be presented, together with some recent results in different research areas, ranging from correlated electron systems to applied materials. Future perspectives for a synchrotron x-ray powder diffraction facility will also be discussed.
