APS Info


The Advanced Photon Source is a synchrotron light source that produces high-energy, high-brilliance x-ray beams. The source is optimized to put large quantities of high-energy photons into a very small area in a very short time.

     The x-ray beam is customized at each beamline to meet particular needs. With more than 40 beamlines already operational, and more under development, the APS offers an exceptionally broad range of experimental conditions at a single facility. It is also conveniently located at Argonne National Laboratory, 30 miles southwest of Chicago, Illinois, with two nearby airports offering many travel options.

     Scientists from around the world come to the APS to conduct forefront basic and applied research in the fields of materials science; biological science; physics; chemistry; environmental, geophysical, and planetary science; and innovative x-ray instrumentation.
