The ALS Diffraction & Imaging Program comprises three diffraction beamlines (small-molecule crystallography, diffraction under non-ambient conditions, and microdiffraction) and one micro-CT imaging beamline. They share a focus on in situ and operando experiments, and all have intense data handling and processing requirements. All four beamlines are situated on superbend sources, providing maximum energies in the hard x-ray region . The hallmark of these instruments is their wide applicability across a broad range of areas, including earth and environmental, materials, chemical, and biological sciences, and beyond. The tools offered by the Diffraction & Imaging Program are highly complementary to the ALS’s soft and tender x-ray programs.
