The complex is intended for carrying out research in the X-ray range at several analytical devices 5 simultaneously. The complex comprises a source 1 of divergent X-rays, for example an X-ray tube and x-ray lenses 2 for radiation transporting toward the analytical devices 5 and the apparatus of these devices. The X-ray lenses 2 form the x-rays into quasi-parallel beams. Usage of the X-ray lenses provides for the scientists in the analytical devices the requisite brightness, being not less than in the complexes where the radiation source is a synchrotron.
