Lightning flashes across the night sky above the Advanced Photon Source at Argonne National Laboratory near Lemont, Ill. The APS, one of the three largest synchrotron light sources in the world, creates high-energy X-rays that can traverse relatively thick objects without being much absorbed or scattered.
