Outline of Final Research Achievements

Using X-ray Dark-Field Imaging optics we have developed improvement of the spatial resolution. The system comprises 2 crystals, one is called asymmetric-cut monochromator-collimator (MC) and the second one is called Laue angle analyzer (LAA). MC has asymmetric angle of 10.2 deg while the Bragg angle was 10.6 deg for 440 diffraction and 35 keV X-rays. As a result of this selection b has become 0.02 that has made the divergence of outgoing beam from MC was 0.05 arc sec. LAA has a relation between its thickness and the spatial resolution by calculation based on Takagi-Taupin theory. The theoretical limit of thickness of LAA is 60 micrometers while in practice there is some technical limit so that we have achieved the spatial resolution of 8.5 micrometers.
