Sb. Dabagov et al., FOCUSING OF X-RAYS BY CAPILLARY SYSTEMS, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 103(1), 1995, pp. 99-105
The structure and form of the focal spot when focusing X-rays in the e
nergy range from 7 keV to 10 keV by Kumakhov lenses were investigated.
It is shown that owing to focusing the radiation concentration abrupt
ly increased. For the first time the interference structure of a focal
spot came to light. Possibilities of using a Kumakhov lens as an anal
yzer with high spectral resolution and as a point source of X-ray radi
ation are discussed.
