Figure 2
Sketch of the experimental arrangement in a vertical (upper panel) and horizontal cut (lower panel). The beam from the insertion devices (AMPW) is guided in vacuum through the first optics hutch OH1 into OH2, where vertical slits define the degree of circular polarization. In experimental hutch B (EH B) the monochromated beam strikes the sample which is held in a permanent-magnet field, and scattered photons are detected by a Ge detector in horizontal backscattering geometry. |
