BEAMLINE GUIDE
ALS 12.2.1


The Advanced Light Source
Berkeley, CA

Beamline 12.2.1 is a small molecule X-ray diffraction facility on the Advanced Light Source at
Lawrence Berkeley National Lab, dedicated to the structural characterization of crystalline
compounds produced by inorganic, organic, organometallic, and materials researchers. The
beamline is built on an ALS superconducting bending magnet that provides a very intense beam
of monochromatic x-rays in the range of 6—25 keV (0.5 — 2 Å), with a beam size around 50 x
50 microns. Data can be collected in a nitrogen stream from 90 to 500K using an Oxford
Cryosystem Cryostream or use using the environmental gas cell to studies gas absorption in
microporous materials such as Metal Organic Frameworks.
