Energy spectra of the neutron beam on the set of analysers for 2.7 meV neutrons (left) and of the neutrons hitting the detector triplet for 5.0 meV (right) for a Y2O3 sample of different sizes. The diameter and height of the cylindrical samples are equal, with the magnitude indicated in the legend. The mosaicity of both the sample and the analyser is 60 arcmin. The lines are only joining the points. |
