Figure 8
The intensity distribution of the monochromatic beam at 50 keV, recorded with a Hamamatsu C9252DK-14 flat-panel detector in SOE-1 (top). The x axis corresponds to width, the y axis to the height of the beam and the z axis presents intensity. The reflectivity curve as recorded with the pin-point TN31014 ion chamber and 0.3 mm (V) slit collimator at 50 keV with Rb2 = 20.8 m and Rb1 = 19.7 m, FWHM = 6.57 × 10−3 degree (0.11475 mrad), or 145 eV or 0.29% (bottom). |
