    Illustration of an electron beam traveling through a niobium cavity—a key component of SLAC’s LCLS-II x-ray laser. It’s kept at 2 kelvins (-456°F), a temperature at which niobium conducts electricity without losses, and these cavities power a highly energetic beam that creates up to 1 million x-ray flashes/second—more than any other current or planned x-ray laser.
    In this Q&A, researchers at the SLAC National Accelerator Laboratory answer our questions about the Linac Coherent Light Source (LCLS) x-ray free-electron laser (XFEL) upgrade...
