Figure 5
Ray tracings showing the image at the focal plane. The source is a 2.6 cm-period undulator (APSU) tuned to 5 keV. Both M1 and M2 mirrors have a C 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. (c) As in (b) after a pitch correction of 288 µrad. Note that the vertical ranges in (a) and (c) are the same but the beam is shifted.
