In this paper a new system is proposed which allow to obtain monochromatic x-radiation of high intensity in a small sized focal spot. It consists of straight monocapillaries combined with mosaic graphite crystals. The capillaries at the entrance side of transport x-radiation from the source to the graphite crystals where it will be monochromatized due to the Bragg effect. A second set of capillaries collect the monochromatized radiation and focus it in a small focal spot. An intensity gain is realized by a parallel radiation transport through many capillaries arranged symmetrically around the optical axis of the system. Testing results of this monochromatizing concentrator for the Mo-K(alpha) line are presented in this paper. A multiple intensity gain of this line is achieved in comparison with the direct x-ray beam.
