This undulator-fed beamline spans an energy range of 8-14 keV. It features multilayer monochromator optics at 0.6% bandpass for high flux, capable of delivering 1012 ph/s into a 100 µm × 100 µm spot size. Microfocusing optics are available to give a beam size down to approximately 10 µm × 10 µm. FlexX currently houses a Eiger2 16M detector. The BAM-2 style automounter accepts Unipucks for fast sample changing. Remote data collection is available for routine experiments. We welcome users who wish to do non-standard experiments that require more time for setup and collection, including serial crystallography, room temperature crystallography, crystallography at high pressure, diffuse scattering, and other experiments.
