Abstract—A substantially new direction in the X-ray microscopy is developed. X-ray images of a microscopic
X-ray source representing a focal spot of a microfocus X-ray tube have been obtained with a spatial resolution
at a level of 1 μm. This possibility is provided by a cone-shaped polycapillary structure of high-resolution
Kumakhov optics. © 2004 MAIK “Nauka/Interperiodica”.
