Tick, Tock on the ‘Attoclock’: Tracking X-Ray Laser Pulses at Record Speeds

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.

Superconducting X-Ray Laser Takes Shape in Silicon Valley

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.
