Figure 14
Maps of elemental distribution for the materials which have relatively low resonance absorption energies as seen in Fig. 13[link]. The range of neutron wavelength at which the images are acquired is indicated in each image. The wide-spectrum images of the same data set are shown in Figs. 4[link] and 6[link]. Images (a)–(d) are normalized by the image integrated over the [18.7 mÅ, 36.4 mÅ] range of wavelengths, where there are no resonances present. Images (e) and (f) are normalized by the white-spectrum open-beam image. Even small variations of Mn concentration (e.g. 0.5–1.7% in our samples) can be resolved, as seen in image (c) (note that the samples have the same 10 mm thickness in that orientation).
