Linac Coherent Light Source (LCLS) Aerial View (image) DOE/SLAC National Accelerator Laboratory Share Print E-Mail Caption This is an aerial view of the Linac Coherent Light Source (LCLS), the world's first hard X-ray free-electron laser. Using SLAC's linear particle accelerator to create powerful X-rays, LCLS pushes science to new extremes with ultrabright, ultrashort pulses that capture atomic-scale snapshots in quadrillionths of a second. These images can reveal never-before-seen structures and properties in matter, and can be compiled to make movies of molecules in motion.
