The newly upgraded Linac Coherent Light Source (LCLS) X-ray free-electron laser (XFEL) at California’s SLAC National Accelerator Laboratory has successfully produced its first X-rays, and researchers around the world are lined up to kick off an ambitious science program. The upgrade, called LCLS-II, now makes it the world’s most powerful X-ray laser, surpassing the European XFEL near Hamburg, Germany.
