Figure 2
(a) Plan view schematic representation of the arrangement of the DCD crystals, diffractometer and another larger detector (P2M) upstream of the diffractometer that can also move to cover the deflected beam. (b) The maximum distance achievable for the P2M detector that will still allow the deflected beam to hit the detector. (c) The variation with X-ray energy of the footprint size (150 µm beam) at the sample position for Qz = 0.021 Å−1 (the critical edge of water). (d) The maximum horizontal deflection β as a function of energy. |
