Abstract

Novel modification of the neutron diffraction method - method of Bragg diffraction angle analysis, which is routinely used for strain/stress investigations in polycrystalline materials in NPI Rez is presented. It provides sufficiently high resolution permitting investigations of both the macro- and microstains of the order 10^-4. Basic feature of the modification is the exploitation of Bragg diffraction optics - focusing in real and momentum space - using curved perfect crystal slabs. Properties of this modification are documented by results of experimental measurements.
