Figure 6
Ray tracings showing the image at the focal plane. The source is a 2.6 cm-period undulator (APSU) tuned to 6.5 keV. Both M1 and M2 mirrors have a Rh optical coating. (a) Assuming slope errors of 0.2 µrad on both M1 and M2. (b) Including the slope errors and the deformation due to the absorbed power in both mirrors. (c) As in (b) after a pitch correction of 179 µrad on M1 and 3.2 µrad in M2. Note that the vertical ranges in (a) and (c) are the same but the beam is shifted. |
