Explaing the process of measuring the reaction with the X-Ray free-electron laser, Sundstrom said: “With the first laser pulse you start the reaction, like shooting the gun when you start a 100m race, and then with a slight delay of a few picoseconds you shoot the second pulse which takes a snapshot of the reaction that started with the first pulse.” Courtesy of RIKEN SPring-8 Center.
