Beamline Optics
The beamline uses as a monochromator a Si(111) channel-cut crystal, fig.1 left.
Due to the silicon d-spacing, the beamline energy is restricted to 5.5 keV - 22.5 keV. The Si channel-cut crystal is cryogenically cooled. The next optical element is a cylindrical focusing mirror, fig. 1 middle, with 1:1 focusing.
The mirror unit is mounted on a bending mechanism, which allows us to dynamically focus the beam. The smallest achievable focus is (70v x 140h) µm FWHM, fig.2. The beamline is also equipped with two CVD diamond windows, fig.1 right.
