Figure 10
Images from the large-area detector taken for strong variations of the grazing incidence angle from about 0.4° to 1.4° on an (slightly different) MM. After double reflection, the beam remains fixed at a detector angle of about 3.4°. At steeper incidence angles above 1.18°, which are far away from the angle in the NewAthena optics, the beam can traverse the pores after a single reflection, and its position depends on the incidence angle.
