AbstractThis article gives a complete account of the research in synchrotron radiation powder diffractometry (SRPD) conducted at DESY/Hasylab between 1981 and 1992 and incorporates an extensive bibliography on SRPD in general. A detailed description of the experimental station for powder diffraction established in fall 1988 at beamline B2 of HASYLAB is given and selected examples of research conducted to date are reviewed to demonstrate its capabilities and potential. Aspects of instrument availability and beamtime allocation are entertained in the concluding remarks. References have been selected such that maximum coverage of the field is achieved with a minimum of citations and the list is hopefully complete with respect to the retrievable literature pertinent to the development of synchrotron powder diffractometry at Hasylab. Papers covering methodical aspects of data analysis and more general aspects of SRPD, however, have not been included.

A compact furnace has been designed and fabricated for measurements of high-resolution synchrotron radiation powder diffraction profiles from materials at high temperatures up to 1807 K in air, suitable for the multiple-detector system installed at the BL-4B2experimental station of the Photon Factory in Tsukuba, Japan. The whole powder pattern of the material at a high temperature can be scanned at a step interval of 0.004° in 2θ, with a counting time of 1.5 s step−1, in just 7 h.

The highly-collimated, intense X-rays produced by a synchrotron radiation source can be harnessed to build high-resolution powder diffraction instruments with a wide variety of applications. The general advantages of using synchrotron radiation for powder diffraction are discussed and illustrated with reference to the structural characterisation of crystalline materials, atomic PDF analysis, in-situ and high-throughput studies where the structure is evolving between successive scans, and the measurement of residual strain in engineering components.

A set of macros based on CERN's program package PAW has been developed for interactive preprocessing of two-dimensional detector data at ESRF prior to more detailed data analysis. Various types of image operations (averaging, cuts, background correction etc.) are available. The main use of the package is at present in small- and wide-angle X-ray scattering (SAXS and WAXS). The flexibility of the package allows, however, easy adaptation to other areas such as fibre or powder diffraction.
