On High-Resolution Reciprocal-Space Mapping with a Triple-Crystal Diffractometer for High-Energy X-rays

K.-D. Liss, A. Royer, T. Tschentscher, P. Suortti and A. P. Williams

Synopsis: The high-resolution triple-crystal diffractometer at the High Energy Beamline at the European Synchrotron Radiation Facility is presented. The reciprocal space mapping is demonstrated at a layer of electrochemically etched macro pores in perfect silicon revealing diffraction satellites corresponding to the modulation.

Time-Resolved Grazing-Incidence Diffraction Studies of Thin Films Using an Imaging-Plate Camera and Focusing Monochromator

G. J. Foran, I. R. Gentle, R. F. Garrett, D. C. Creagh, J. B. Peng and G. T. Barnes

Synopsis: A multiple imaging-plate detector system and focusing mono- chromator have been developed and successfully employed at the Australian National Beamline Facility at the Photon Factory. The utility of the system has been demonstrated through the study of temperature-dependent phase transitions in LB films of metal fatty acids by grazing-incidence X-ray diffraction.
