Figure 7
Monochromatic beam from the artificial channel-cut monochromator imaged using a CCD detector, showing a highly improved uniformity in the intensity distribution compared with that from the traditional channel-cut shown in Figs. 1(a)–1(c). The intensity cross section measured using a 20 µm × 20 µm aperture on a PIN diode point detector (b) in the horizontal and (c) in the vertical direction. |
