A general view The diffractometer D2B is characterised by the very high take-off angle (135°) for the monochromator, which has a relatively large mosaic spread of 20’ to compensate for the corresponding ... 50 mm; this large incident vertical divergence is matched by 200 mm high detectors and collimators. A complete diffraction pattern is obtained ...
