When it comes to making molecular movies, producing the world’s fastest X-ray pulses is only half the battle. A new technique reveals details about the timing and energy of pulses that are less than a millionth of a billionth of a second long, which can be used to probe nature’s processes at this amazingly fast attosecond timescale.
Combining X-ray and electron data from two cutting-edge SLAC instruments, researchers make the first observation of the rapid atomic response of iron-platinum nanoparticles to light. The results could help develop ways to manipulate and control future magnetic data storage devices.
The first cryomodule has arrived at SLAC. Linked together and chilled to nearly absolute zero, 37 of these segments will accelerate electrons to almost the speed of light and power an upgrade to the nation’s only X-ray free-electron laser facility.
