Picosecond Structural Dynamics at the Advanced Photon Source

The paradigm “structure determines function” has long been a motivation for X-ray structural studies. However, the understanding of function can go well beyond static pictures with atomic resolution, as one explores the time domain with short-pulse X-rays. The U.S. Department of Energy's Advanced Photon Source (APS) at Argonne National Laboratory is home to a suite of science techniques and facilities that exploit the short-pulse nature of X-rays to probe structural dynamics in chemical, biological, condensed matter, and atomic/molecular systems.
