Peetermans, S.Lehmann, E. H.2013-12-092013-12-092013-12-09201310.1063/1.4823741https://infoscience.epfl.ch/handle/20.500.14299/97772WOS:000325391100081Traditional neutron tomography allows to reconstruct the attenuation cross section, a measure for the material distribution, at high spatial resolution and non-destructively. However, it does not state anything about the ordering structure of the atoms inside this material. Extending the setup with a second neutron imaging detector, diffracted neutrons from the ordered crystal lattice could be captured. Emerging iterative reconstruction techniques allow reconstructing the local Bragg reflectivity in the sample, a measure for the spatial distribution in crystal quality (orientation, homogeneity of phases). Simultaneous acquisition ensures optimal use of the neutron flux and a direct comparison of different sample properties. (C) 2013 AIP Publishing LLC.text::journal::journal article::research article
