Figure 4
Attenuation coefficients for Fe, Cu and V computed using nxsPlotter data and the spectra from the different beamlines. They are split into the following contributions: coherent elastic, coherent inelastic, incoherent elastic, incoherent inelastic and absorption. The bar diagrams show the behaviour of Fe, Cu and V in a thermal spectrum (NEUTRA), thermal and cold (ICON), cold (BOA), and cold with beryllium (Be) filter. The Be filters out neutrons below 4 Å, thus leaving only the cold tail of the neutron spectrum and greatly reducing the effect of Bragg scattering. |
