Suppressing Diffraction-Related Intensity Losses in Transmissive Single-Crystal X-ray Optics

The highest-quality X-ray optics can be made of single-crystal materials such as silicon, germanium, or, even better, diamond. Unfortunately, have one drawback: diffraction losses or the “glitch effect”. This effect manifests itself follows: at some energies X-rays, intensity transmitted beam drops due to fact that crystalline planes satisfied condition. Diffraction are usually observed in spectroscopic experiments when energy X-rays changes a certain range. However, this might also influence any experiment using especially higher energies. In paper, we propose method overcome glitch problem transmissive optics. is achieved small rotations optical element. We describe algorithm for “glitch-free” measurements detail and theory behind it.
