High-Resolution X-ray Diffraction Experiments Using Synchrotron Radiation

Photograph of the BIGDIFF with the open drum.

Experimental set-up for triple-crystal diffractometry using BIGDIFF at beamline 20B of the Photon Factory synchrotron source. The large drum housing the diffractometer can be evacuated to reduce air scattering. BIGDIFF is installed at the Australian National Beamline Facility (ANBF), Photon Factory, KEK, Tsukuba, Japan.

Omega-slice scans throuth the Bragg peaks for the case where the surface oxide layer is (a) present and (b) removed (A. Y. Nikulin, et. al., J. Appl. Cryst., 28, 803 (1995).). The data have been scaled so that the maxima for the data sets correspond to the calculated peak reflectivity values for a perfect Si(111) crystal.
