The optics common with the diffraction beamline consists of:
· Carbon-Filter to reduce the power load on the first optical elements by a factor of 2
· Beryllium windows to separate the beamline vacuum from the storage ring
· Beam defining slit chamber before the SAXS monochromator
The SAXS beamline optics consists of:
· A double-crystal monochromator
· A baffle chamber after the monochromator is used as an adjustable straylight fenditure
· A segmented toroidal mirror focuses the light in horizontal and vertical direction with a 1/2.5 magnification onto the SAXS-detector
· An aperture slit reduces the straylight after the monochromator and the toroidal mirror
· A guard slit defines the illuminated region on the sample
