While SLAC's Linac Coherent Light Source was designed to push the limits as a high-energy X-ray laser, users' requests have led staff at the facility to successfully step it back to a lower minimum energy for some experiments.
The DOE has approved the project’s scientific scope, schedule and funding. SLAC researchers are among the 200 physicists and astronomers who make up the international DESI Collaboration.
X-ray research on 80-million-year-old fossilized burrows, likely the work of tiny marine worms, is helping scientists understand how living organisms affected the chemistry of the sea floor.
