Figure 14
The crystal-integrated angular dependences of Bragg reflectivity (rocking curves) of the crystals used in these experiments: (a) the reference silicon crystal in the 531 Bragg reflection, and diamond crystals (b) VB5, (c) VB6 and (d) D3 in the 400 Bragg reflection. The Bragg reflection widths (FWHMs) are (a) 10.3 µrad, (b) 17.0 µrad, (c) 17.5 µrad and (d) 18.7 µrad. The measurements were performed in the double-crystal C1–C2 arrangement shown schematically in Fig. 13 with an Si PIN diode used instead of the pixel detector. See text for more details. |
