Resolution of a bent‐crystal spectrometer for X‐ray free‐electron laser pulses: diamond versus silicon
(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 ... -
X-ray diffraction from strongly bent crystals and spectroscopy of X-ray free-electron laser pulses
(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 ...
