Figure 9
The position of crystal analysers and detector is determined starting from the one crystal analyser case (a). The Cartesian reference system is also shown. Two successive rotations are applied as explained in the text; their effect can be seen in panels (b) and (c), respectively. Panels (d) and (f) show the crystal analysers and detector position, as well as their surface normals in the two configurations, d > 0 and d < 0. Panel (e) shows the crystal analysers assembly and the crystals analysers and detector local coordinate systems. |
