All Systems Go: A New High-energy Record for LCLS

John Hill watched with eager anticipation as controllers ramped up the power systems driving SLAC's X-ray laser in an attempt to achieve the record high energies needed to make his experiment a runaway success.

The Brookhaven National Laboratory scientist was the leader of a research team that had come from Illinois, Germany, Switzerland and England to use the Linac Coherent Light Source (LCLS), and this was their last day. They would get only one shot.

Fifth X-ray Instrument at LCLS Debuts, With a Bead on Disorderly Structures

After five night shifts of shooting pairs of X-ray pulses through soups of fine sand and gold, Aymeric Robert was tired but exhilarated. The first experiment with an instrument he helped bring into being – the X-ray Correlation Spectroscopy (XCS) instrument at SLAC’s Linac Coherent Light Source – had just ended, launching a new tool for understanding liquids, glasses and other less-than-orderly substances.
