Imagine being able to watch the inner workings of a chemical reaction or a material as it changes and reacts to its environment—that's the sort of thing researchers can do with a high-speed "electron camera" called the Megaelectronvolt Ultrafast Electron Diffraction (MeV-UED) instrument at the Linac Coherent Light Source (LCLS) at the U.S. Department of Energy's SLAC National Accelerator Laboratory.
