mySpot Beamline is used to provide stable beam especially tuned for the mySpot experiment. Depending on the experiment requirements, different optical devices are used. The schematic view shows two different configurations, one tuned for low divergency, and one for narrow energy band width, as required for the scattering and spectroscopy experiments respectively. Since the goal of the experiment is to provide several methods at the same time, beamline properties can be tuned to provide the optimal beam for a given combination of experiments. Total intensity, divergence, energy resolution, high harmonics suppression, and stability in scans can be tuned to match the requirements. For details, please visit the experiment page.

Except 3 different monochromators, the beamline features the second, bimorph adaptive mirror, which is used to vertically focus the beam below 50µm. The mirror has 3 tracks, which are used for the suppression of higher harmonics.
