Figure 5
The water scattering simulated as a function of the scattering vector magnitude Q. The dashed black curve displays the water scattering for a reactor-based instrument at 5 Å wavelength. The red curve shows simulated water scattering for the ISIS instrument SANS2d, with statistical weight from the intensity of the spectrum of a cold source. The green curve shows a simulation of the same instrument with equal weights for each λ slice. The fringes at high Q result from the distinct binning of λ slices at intervals of 0.25 Å. The blue curve displays experimental data from a 50:50 mixture of H2O/D2O measured on SANS2d. |
