Beamline Information

The Insertion Device (ID) for the DCS is a Revolver Undulator that can be switched between two periods, 27 and 30 mm, and thereby allows continuous spectral tuning in energy from 7 to 100 keV.

The beamline optics are designed to deliver four X-ray beam modes that can be fine-tuned in energy, beam-size, bandwidth, and flux to deliver the appropriately conditioned beam for a particular experiment. For example, broad-band white beam is particularly useful for high-energy Phase Contrast Imaging (PCI) while narrow-bandwidth monochromatic beam (~0.01% Bandwidth (BW)) may be used for precision diffraction measurements. Focused pink beam (1-5 % BW) is most useful for obtaining a series of high-flux, single-pulse snapshots where only a single ~100 ps X-ray burst is recorded per frame on an area detector.
