Using diffraction losses of X-rays in a single crystal for determination of its lattice parameters as well as for monochromator calibration [PDF]
Journal of Synchrotron Radiation, 2022 A way has been developed to measure the unit-cell parameters of a single crystal just from an energy scan with X-rays, even when the exact energy of the X-rays is not well defined due to an error in the pitch angle of the monochromator.

Diffraction losses in ground-based optical interferometers [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 We present a numerical analysis of free-space propagation of the beams inside a long-baseline optical/infrared interferometer. Unlike the models of beam propagation used in most previous studies, our analysis incorporates the effects of atmospheric seeing on the wavefronts entering the interferometer.

Approximate methods for calculating multiple-diffraction losses
Electronics Letters, 1966 Keller's geometrical theory of diffraction applied to multiple diffraction leads to useful formulas and supports a general construction, already proposed, for estimating the total diffraction loss. The theory gives a result for two knife edges in tandem which is shown to be equivalent to that obtained by the Epstein-Peterson method plus Millington's ...

Suppressing Diffraction-Related Intensity Losses in Transmissive Single-Crystal X-ray Optics
Crystals, 2021 The highest-quality X-ray optics can be made of single-crystal materials such as silicon, germanium, or, even better, diamond. Unfortunately, such X-ray optics have one drawback: diffraction losses or the “glitch effect”.

X-ray diffraction method application to assess the energy losses on explosive-rock contact under various blasting [PDF]
E3S Web of Conferences, 2020 The dissipative energy losses of the explosion on the explosive-rock contact are usually evaluated with comparative analysis of the particle size distribution of finely dispersed fractions (0-100 microns).
