The efficiency of soft X-ray diffraction gratings is examined using theoretical calculations with new open-source software, and insights to design a high-performance emission spectrometer are applied. The calculated and measured efficiencies of real-world gratings are compared, and discrepancies are explained by incorporating real-world effects into the calculations.

Detector response functionals are found to have useful but also limited application to synchrotron studies where bunched fills are becoming common. By matching the detector response function to the source temporal structure, substantial improvements in efficiency, count rate and linearity are possible.

Metal-oxide tunnel junctions made by optical lithography were studied by X-ray diffraction (imaging approach with diffraction contrast) to access local distortions of the crystalline planes of the constituting layers. The effect of the size (10–150 µm) and shape (disc, square and rectangle) of the junction was investigated.
