Did you know that scientists have the ability to make “movies” of atomic and molecular processes? For this they use an X-ray free-electron laser or XFEL, like the one here at SLAC to capture sequences of ultrafast snapshots! An XFEL produces extremely intense and short X-ray pulses. These pulses are super-fast flashes of light used to probe motions on the atomic scale. When these intense X-ray pulses interact with a sample, a specialized detector produces a series of snapshots that capture the step-by-step progression of a process. Each snapshot reveals the positions of the atoms and molecules at a specific moment in time. When these snapshots are combined and played in rapid succession, just like frames of a movie, it allows scientists to observe the motions of the atoms and molecules. They can see how they rearrange, vibrate, or interact with each other during chemical reactions or biological processes. In essence, XFELs act as high-speed cameras, providing scientists with an unprecedented view of the atomic world, allowing them to unravel the mysteries of ultrafast, ultrasmall processes and gain deeper insights into the fundamental workings of matter.
