Fig. 104: A schematic view of the high-angular resolution camera set up on the beamline ID2. A monochromatic Si 111, two reflections channel cut) and harmonic-removed (toroidal mirror) beam is sent on a channel-cut 1 (Si-220, three reflections in the horizontal plane). The rocking curve (background) and the sample scattering are analysed with two crossed analysers and with crystal 4 (Si-220 with three reflections in the horizontal plane for the rock and a Si-111, two reflections in the vertical plane at a fixed and optimised position for the vertical resolution).
