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”.

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.

Design and testing of a Kirkpatrick-Baez optics variation [PDF]
EPJ Web of Conferences, 2022 Beside Wolter I X-ray optics, which are used at most in currently operating X-ray space telescopes, there exist also other optical designs and their usability for space observations is still the matter of studies.

Journal of Physics: Conference Series, 2009 This paper describes reflective adaptive/active optics for applications including studies of biological radiation damage. The optics work on the polycapillary principle, but use arrays of channels in thin silicon. For optimum performance the x-rays should reflect once off a channel wall in each of two successive arrays.

Graphite Optics—Current Opportunities, Properties and Limits
Condensed Matter, 2019 X-ray graphite optics consists of thin layers of Pyrolytic Graphite (PG) attached to a substrate of focusing shape. Pyrolytic Graphite is a perfect artificial graphite obtained by annealing of carbon deposit at temperatures about 3000 °C under ...

Optical, x-ray and microwave diagnostics
AIP Conference Proceedings, 2013 Laser-driven ion acceleration is a new approach for the particles acceleration, which allows obtaining ion beams with unique properties, such as short burst duration, large particle number, small size source size, low transverse emittance. Currently, two main acceleration mechanisms have been identified and investigated: target normal sheath ...
