3. Devices with polycapillary X-ray microbeams
Nowadays, based on the polycapillary optics, new-generation devices are developed, and
made commercially accessible [2,11], e.g. laboratory synchrotron [4–7], fluorescent spectrometers,
reflectometers/refractometers, diffractometers, X-ray microscopes [12,13] and
combinations of several devices.
Besides, many devices can be developed for the most modern research problems such
as nanomateriology that includes X-ray nanoscanner and X-ray nanothickness indicator
based on X-ray small-angle scattering and X-ray interferometry. Determination of the
size, form and concentration of nanoparticles, interstices and technologically created
details of the structure, and also the measurement of characteristic distances between
them are carried out by X-ray small-angle scattering. X-ray interferometry method is the
most exact and unequivocal for the measurements of layer thickness for any material in
nanometer ranges.
The miniature X-ray tube enables unique capabilities when combined with polycapillary
optics because of the possibility of putting optics very close to anode. Such supercompact
geometry makes it possible to obtain superbright X-ray fluxes from microfocus
low-power X-ray tubes after polycapillary optics [4–7]. Miniature X-ray tubes and radiators
[14], specially developed for use in combination with polycapillary optics and
allowing as much efficiency as possible to use it, can be used in all devices describedhere.
