One of the most important features of the developed portable diffractometer making use of Kumakhov's half-lens is that allows stress strain analysis in different sections of the investigated object. Here the investigation results are presented showin

Different radial capillary layers give different contributions in x-ray radiation field at Kumakhov lens of halflens exit. In case of halflenses transforming divergent beams into quasiparallel ones it can essentially influence an exit quasiparallel b

This paper suggests the scheme of a diffractometer for phase and crystal structure analysis of inorganic matter, where the Kumakhov's capillary half-lens is used as the collimation system. Goniometer-free design of the diffractometer enables applicat

The main component in the x-ray layout of the portable diffractometer is Kumakhov's focusing capillary lens with a certain x-ray convergence angle of ~1-3°, permitting a benchmark determination of a monocrystal plates crystallographic orientation us

It is known that polycapillary half-lenses and lenses limit x-ray energy both in low and high eneryg area, i.e. they create an energy transmission range from 2 to 20 keV. This enables use of the lenses as filters wihtin a wide energy range. The effec
