Figure 12
Time-averaged neutron energy spectra at the sample and the scattering characterization system with a Y2O3 single-crystal sample in McStas (a) and Geant4 (b) simulations. Incident beam on sample (in blue), beam transmitted through the sample (in orange), beam on the set of analysers for 2.7 meV neutrons (in green), beam on the set of analysers for 5.0 meV neutrons (in red), neutrons hitting the detector triplet for 5.0 meV (in purple), beam transmitted through all sets of analysers (in brown). The lines are only joining the points. |
