Figure 1
General illustration of the neutron scattering under grazing-incidence conditions. S – specular, D – diffuse scattering. The orange dashed line on the detector divides the scattering pattern into two regions: GIS, where grazing-incidence scattering is detected, and TS, where signal from transmitted scattering and the direct beam is detected. The white arrow on the 2D detector indicates the Yoneda peak (YP) and DB is the direct beam. The direct beam is usually blocked by a beamstop to avoid detector damage (black square). See the animation in the supporting information (this is a video illustration of the principles of grazing-incidence scattering).
