Ultimate characteristics of an X-ray prism spectrometer
Instruments and Experimental Techniques, 2009X-ray prism spectrometry schemes for experimental investigations of fast processes are considered. Diamond and beryllium prism dispersion parameters and special features of transmission spectra for crystal prisms are analyzed. It is shown that relative energy resolution E/ΔE at photon energies E ∼ 10 keV may reach 103–104 and the total working spectral

Edge diffraction effect at the refraction of X rays in a diamond prism
JETP Letters, 2014The refraction of monochromatic X-ray radiation in an optically polished diamond prism has been studied. Measurements have been performed on the ID10 channel of the ESRF synchrotron (Grenoble). It has been found that parabolic geometric deviations of the profile of the refractive face of the prism from a plane are responsible for the interference ...

Two-Beam X-Ray Holography Using Prism Optics
Japanese Journal of Applied Physics, 2005Two-beam X-ray holography has been developed. A prism made of acrylic resin is used as a beam deflector for a hard X-ray wavefront dividing interferometer. The holographic imaging using this configuration is the same as that of the Leith-Upatnieks-type two-beam holography in the visible light region. Two-parallel-beam holography using a synchrotron

X-ray Interferometer Using Prism Optics
AIP Conference Proceedings, 2004Two‐beam X‐ray interferometer using refractive optics has been developed. A prism made of acrylic resin is used as the beam deflector for hard X‐ray wavefront dividing interferometer. This configuration is the same as that of the Fresnel’s bi‐prism interferometer or the Leith‐Upatnieks type two‐beam holography in visible light region.

Measurements of X-ray absorption spectra by the prism spectroscopy method
Journal of Experimental and Theoretical Physics Letters, 2004X-ray absorption spectra of a number of samples were measured in the range 5–30 keV by the prism spectrophotometry method. The spectral decomposition was performed using an optically polished diamond prism with an opening angle of 90°. The absorption spectra of liquid bromonaphthalene are presented as an example.

X-ray diffraction order selection with a prism in DEI (abstract)
Review of Scientific Instruments, 2002The refraction angle of x rays as they pass through a refractive prism is proportional to the square of the x-ray wavelength. This was used to discriminate between different harmonic orders, which have different energies, created by a two-crystal 111 monochromator [Z. Zhong, J. Appl. Crystallogr 33, 1082 (2000)].

Prism arrangement in human cusp enamel deduced by X-ray diffraction
Archives of Oral Biology, 1982Analysis of the many X-ray diffractograms obtained from the regions along the bands of Hunter-Schreger, and a series of X-ray patterns taken by tilting the specimen with respect to the incident X-ray beam over a wide range of tilt angles, showed that the fibre axis of the crystal aggregates in each zone of the bands not only deviated in opposite ...

Determination of anomalous scattering factors in GaAs using x-ray refraction through a prism
Physical Review B, 1985The advantages of synchrotron radiation have been employed to revitalize a 60-year-old technique for measuring anomalous scattering factors by accurately measuring x-ray refraction through a prism. We report results obtained from a GaAs sample in the vicinity of both the Ga and As K absorption edges.

Two-Beam X-Ray Interferometer Using Prism Optics
Japanese Journal of Applied Physics, 2002A holographic imaging method in the hard X-ray region is proposed. Two-beam interferometer is realized by using an X-ray prism as the beam deflector. A portion of fully coherent X-ray beam is deflected by the prism, and superimposed on the object wave at the image plane.

Advances in the development of x-ray refractive large aperture rolled prism lenses
SPIE Proceedings, 2011At the Institute of Microstructure Technology (IMT) at Karlsruhe Institute of Technology (KIT) X-ray refractive line focus lenses have been developed. They consist of a large number of concave bi-parabolic lens elements made of SU8. To form a point focus two of these lens stacks, tilted by 90° with respect to each other around the optical axis, need ...
