Paper Abstract

The spatial resolution of the modern x-ray and neutron detectors is limited by the range of secondary particles. It was shown theoretically that polycapillary Kumakhov optics can avoid this limit. Such systems can provide resolution less than 1 micrometer for energy 17 keV even using ordinary x-rays sources and detectors. The results of experimental investigations of polycapillary cone for imaging of objects with micron level resolution are present. This work is an extension of our last report at SPIE-96. New technology allows us to decrease the entrance capillary diameter to 0.5 micron. On this base we received resolution on the level 1.5 - 2 microns.
