A $1.1 billion upgrade more than a decade in the making, the x-ray free-electron laser (XFEL) is now capable of firing 1 million x-ray pulses per second—8000 times as many as the first-generation LCLS, which began operation in 2009. Each pulse is 10 000 times as bright as those of the original LCLS.

The agency warned that such materials could be used to fashion a radiological dispersion device, commonly known as a dirty bomb, that could cause hundreds of deaths and billions of dollars’ worth of damage.
