During the last several years we have seen intense development of the capillary optics. This fact is connected with improvement of the capillary optics technology. One of the important last achievements in this development is the use of capillary lenses for receiving intense polarized x-ray beams. This experiment was carried out at the Institute for Roentgen Optics (IRO). The new x-ray florescent analyzer was constructed by IRO. We have received minimal detection limit 10-13g using portable small power x-ray tube (approximately 1 - 2 W) and the capillary lens. On the basis of new technology, which was made for the first time in our Institute, we had success in the imaging of thick samples with micron level resolution. Last year, in collaboration with scientists from Europe, we carried out the experiments in focusing of neutron beams in atomic reactors. These experiments demonstrated that capillary optics provide record concentration of neutron beams.
