Scientists Drive Tiny Shock Waves Through Diamond

Researchers have used an X-ray laser to record, in detail never possible before, the microscopic motion and effects of shock waves rippling across diamond. The technique, developed at the Department of Energy's SLAC National Accelerator Laboratory, allows scientists to precisely explore the complex physics driving massive star explosions, which are critical for understanding fusion energy, and to improve scientific models used to study these phenomena.
