Beamline I911-1 is presently equipped with set-up for nano-science and x-ray physics education. It is one out of five experiment stations at beamline I911. The experiment hutch includs a set-up for fluorescence measurements to determine x-ray scattering factors and to scan an absorption edge (x-ray physics education) and a set-up for studying mono-layers on a water substrate with grazing incidence measurements using the synchrotron radiation and reflectivity measurements using an additional x-ray source.

I911-1 is planned to eventually be equipped as a fixed wavelength station for macromolecular crystallography. The wavelength, 1.25 Å, for the future macromolecular crystalllography station is chosen to have a high flux and somewhat longer wavelength than the other fixed wavelength stations at I911. The beam is first monochromatized and horizontally focused by a planar diamond crystal working in Laue geometry and then focused in the vertical by a 400 mm, curved multi-layer mirror. The high-flux photon beam is produced by a super-conducting multi-pole wiggler.
