  • Confocal energy-dispersive X-ray diffraction tomography employing a conical shell beam 
    Dicken, Anthony; Evans, J. Paul O.; Rogers, Keith; Prokopiou, Danae; Godber, Simon; Elarnaut, F.; Shevchuk, Alex; Downes, D.; Wilson, M. (Optical Society of America, 2019-07-01)
    We introduce a new high-energy X-ray diffraction tomography technique for volumetric materials characterization. In this method, a conical shell beam is raster scanned through the samples. A central aperture optically ...
  • High energy transmission annular beam X-ray diffraction 
    Dicken, Anthony; Shevchuk, Alex; Rogers, Keith; Godber, Simon; Evans, Paul (Optical Society of America, 2015-02-02)
    We demonstrate material phase retrieval by linearly translating extended polycrystalline samples along the symmetry axis of an annular beam of high-energy X-rays. A series of pseudo-monochromatic diffraction images are ...
  • A new parafocusing paradigm for X-ray diffraction 
    Prokopiou, Danae; McGovern, James; Davies, Gareth; Godber, Simon; Evans, Paul; Dicken, Anthony; Rogers, Keith (International Union of Crystallography, 2020-07-24)
    A new approach to parafocusing X-ray diffraction implemented with an annular incident beam is demonstrated for the first time. The method exploits an elliptical specimen path on a flat sample to produce relatively high ...
