Analysis of small‐angle scattering data of interacting ellipsoids using pair distance distribution functions

Journal of Applied Crystallography, EarlyView.
Pair distance distribution functions of interacting ellipsoidal particles can be hard to interpret. This difficulty can be circumvented partially by the generalized indirect Fourier transformation.Pair distance distribution functions (PDDFs) similar to those obtained by indirect Fourier transformation of small‐angle scattering data from interacting ...

GIWAXS using microbeam applied in halide perovskite films for high spectral resolution and mapping capability

Journal of Synchrotron Radiation, EarlyView.
This article demonstrates that microbeam GIWAXS (µ‐GIWAXS) effectively overcomes the distorting footprint effects of conventional GIWAXS analysis of perovskite films. This advancement not only delivers higher reciprocal‐space resolution data but also unlocks the unique capability to spatially map microstructural inhomogeneity, which is vital for the ...

Diffractive wavefront correction for Fe L‐edge spectroscopy on the meV scale

Journal of Synchrotron Radiation, EarlyView.
We propose an aberration‐corrected, wavelength‐dispersive instrument for soft X‐ray spectroscopy at an energy‐resolving power of (5–6) × 104, designed for, for example, resonant inelastic X‐ray scattering at synchrotron beamlines or X‐ray free‐electron lasers.We propose a wavelength‐dispersive instrument for high‐resolution soft X‐ray spectroscopy at ...

MIDAS: a methodological framework for high‐speed high‐energy diffraction microscopy data reduction. Part I: methodology

Acta Crystallographica Section A, EarlyView.
This paper details the complete methodological framework implemented in the MIDAS software for processing high‐energy diffraction microscopy (HEDM) data. We describe the specific algorithms, coordinate systems and physical models used for both far‐field and near‐field HEDM analysis.
