    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.
