“…Capillary optics is one of the fastest growing X-ray optical technologies (Pfeiffer et al, 2002;Sun et al, 2009) because of its superior capacity of generating high-flux-density beams in the micrometre and submicrometre range. The properties and peculiarities of X-ray beams formed by polycapillary optics have been intensively studied over the past 20 years (Kumakhov & Komarov, 1990;Bilderback et al, 1994;Dabagov et al, 1995;Dabagov & Uberall, 2007).…”

Here, soft X-ray synchrotron radiation transmitted through microchannel plates is studied experimentally. Fine structures of reflection and XANES Si L-edge spectra detected on the exit of silicon glass microcapillary structures under conditions of total X-ray reflection are presented and analyzed. The phenomenon of the interaction of channeling radiation with unoccupied electronic states and propagation of X-ray fluorescence excited in the microchannels is revealed. Investigations of the interaction of monochromatic radiation with the inner-shell capillary surface and propagation of fluorescence radiation through hollow glass capillary waveguides contribute to the development of novel X-ray focusing devices in the future.

“…Capillary X-ray optics (CXRO) plays an important role in the development of X-ray technology, and it has many application fields, such as chemistry, physics, life science, materials science, environmental control, mineral resources, drug analysis, and security check (Janssens et al 2000, Wegrzynek et al 2005, Albertini et al 2007, Sun et al 2009a, Yonehara et al 2010, Scharf et al 2011, Evens et al 2012. CXRO, which works on total external reflection, includes monocapillary X-ray optics (MXRO) (Hirsch and Kellar 1951) and polycapillary X-ray optics (PXRO).…”

Capillary X-ray optics is versatile, and it can be used with synchrotron radiation source, conventional X-ray source, laser-plasma ultrafast X-ray source, and so forth. Recently, the confocal X-ray technology based on capillary X-ray optics has become popular, and it has been widely used in X-ray fluorescence, X-ray absorption fine structure, X-ray diffraction, small-angle X-ray scattering, X-ray imaging, and X-ray scattering. This confocal X-ray technology has applications in many fields, including environmental monitoring, food science, life science, chemistry, physics, nanomaterials, nondestructive test, security check, and so on.

“…The monochromatic X-ray imaging setup can be based on synchrotron radiation in order to obtain adequate intensity [3,4]. This lack of magnification results in a need for an improved spatial resolution of the detector system [4]. If a conventional X-ray source is used with a flat monochromator crystal, only the small fraction of the beam within the angular bandwidth of the crystal will be diffracted.…”

“…This lack of magnification results in a need for an improved spatial resolution of the detector system [4]. Previously, a monochromatic X-ray imaging system using synchrotron radiation and a plane monochromator followed by a polycapillary half focusing X-ray lens had been demonstrated [4]. A doubly cured crystal used to perform X-ray imaging can provide magnification.…”

A monochromatic X-ray imaging setup based on a combination of a doubly curved crystal and a polycapillary focusing X-ray lens was designed. In this setup, the bent crystal optic was used not only to monochromatize but also to focus the divergent X-ray beam from a conventional X-ray source to form a monochromatic X-ray focal spot with a size of 426 × 467 µm 2 at 17.5 keV. The beam expanding from this focal point was focused by the polycapillary optic to obtain a focal spot which was then used as the monochromatic X-ray imaging virtual source. The output focal spot size of the focusing polycapillary optic at 17.5 keV was 97 µm. Compared with the beam expansion after the focal spot of the bent crystal optic, the beam expansion after the focal spot of the focusing polycapillary optic was relatively large. This was helpful for magnifying the X-ray image of the sample. The focused beam was helpful to decrease the exposure time for imaging small samples.
