The SLS Optics Beamline

A multipurpose beamline for tests and developments in the field of x‐ray optics and synchrotron radiation instrumentation in general is under construction at the Swiss Light Source (SLS) bending magnet X05DA. The beamline uses a newly developed UHV compatible, 100 μm thick, brazed CVD diamond vacuum window. The very compact cryogenically cooled channel cut Si(111) monochromator and bendable 1:1 toroidal focusing mirror at 7.75m from the source point are installed inside the shielding tunnel. The beamline covers a photon energy range of about 6 to 17 keV. We expect 5 ⋅ 1011 photons/s within a 100 μm spot and a resolving power of 1300. The monochromator and focusing mirror can be retracted independently for unfocused monochromatic and focused “white” light operation respectively.
