AbstractThe effect of double-crystal neutron focusing, using Laue diffraction in large perfect crystals was studied. The observed effect allows reach the angular resolution better than 0.03", that is ~ 10-2 of the Bragg reflection width. This fact makes it possible to create a new ultraprecise method for neutron spectrometry combining the spin-echo small angle neutron scattering with Laue diffraction. J. Phys.: Conf. Ser. 746 (2016) 012049
