Figure 5
Incident intensity profile measured from 18.4 to 18.5 keV. The scans were repeated with the axes fully synchronized (black line: optimum) and with the downstream axis deliberately set away from this optimum setting. The cyclic oscillations due to the interpolation errors are only visible when the axes are not completely synchronized. An offset of 0.1 eV at this energy corresponds to about 0.6 µrad angular misalignment between the two axes. |
