Serial X-ray crystallography (SX) is used for data collection at X-ray Free Electron Lasers. Here the authors show that a polychromatic “pink” synchrotron X-ray beam can be used for SX, which is useful when crystal supply is limited and will allo

Small x-ray beam sizes necessary for probing nanoscale phenomena require exquisite stability to prevent data corruption by noise. One source of instability at synchrotron radiation x-ray beamlines is the slow detuning of x-ray optics to marginal alig

X-ray interferometry has been used to study the profile structures of chemisorbed alkylsiloxane (hexadecyl-, octadecyl-, and eicosyl-) monolayer films on Ge/Si multilayer substrates of the type 2(Ge 2 Si 30 ), i.e., two superlattice unit cells, each

Since 2007, we have offered single collimators for mini beams of sizes 5, 10 and 20 µm as well as a 300 µm scatter-guard to accommodate the fully focused beam. The advantages of varying the beam size were obvious, better signal/background ratio and

In the last several years, Kirkpatrick‐Baez (K‐B) mirror systems have been extensively applied as two‐dimensional x‐ray focusing elements on x‐ray beamlines at low emittance, third generation, synchrotron radiation facilities. The design of

A typical problem encountered on a beamline with a sagittal focusing monochromator is the difficulty of optimizing the crystal alignment because the full width of the monochromatic, unfocused beam cannot be visualized. This problem is particularly ac

The stability of the particle beam position and angle on third generation synchrotron sources such as the Advanced Photon Source (APS) at Argonne National Laboratory is extremely good. However, because of the long length of beamlines (50–70 m) at s
