Resolution of a bent‐crystal spectrometer for X‐ray free‐electron laser pulses: diamond versus silicon
Kaganer, Vladimir M.; Petrov, Ilia; Samoylova, Liubov (Acta Crystallographica Section A, 2021-05-27)The resolution function of a spectrometer based on a strongly bent single crystal (bending radius of 10 cm or less) is evaluated. It is shown that the resolution is controlled by two parameters: (i) the ratio of the lattice ... -
Small‐angle X‐ray scattering from GaN nanowires on Si(111): facet truncation rods, facet roughness and Porod's law
Kaganer, Vladimir M.; Konovalov, Oleg V.; Fernández-Garrido, Sergio (Acta Crystallographica Section A, 2020-12-24)Small‐angle X‐ray scattering from GaN nanowires grown on Si(111) is measured in the grazing‐incidence geometry and modelled by means of a Monte Carlo simulation that takes into account the orientational distribution of the ... -
X-ray diffraction from strongly bent crystals and spectroscopy of X-ray free-electron laser pulses
Kaganer, Vladimir M.; Petrov, Ilia; Samoylova, Liubov (Acta Crystallographica Section A, 2019)The use of strongly bent crystals in spectrometers for pulses of a hard X-ray free-electron laser is explored theoretically. Diffraction is calculated in both dynamical and kinematical theories. It is shown that diffraction ...
