Ribosome Research Takes Shape at SLAC

In a new state-of-the-art lab at SLAC National Accelerator Laboratory, components of ribosomes – tiny biological machines that make new proteins and play a vital role in gene expression and antibiotic treatments – form crystals in a liquid solution.

Signs at the lab's entryway warn of the potential for contamination – these delicate samples can be damaged by human touch, a sneeze or a dust particle.

Rapid Beam-switching Allows SLAC X-ray Laser to Multitask

A high-energy SLAC laser that creates shock waves and superhot plasmas needs to cool for about 10 minutes between shots. In the meantime, the rapid-fire pulses produced by SLAC's Linac Coherent Light Source X-ray laser, which probes the extreme states of matter produced by this initial laser shot, are unused.

A New Tool to Split X-ray Laser Pulses

A new tool at SLAC's Linac Coherent Light Source splits individual X-ray laser pulses into two pulses that can hit a target one right after another with precisely controlled timing, allowing scientists to trigger and measure specific ultrafast changes in atoms and molecules.

New Test Bed Probes the Origin of Pulses at LCLS

It all comes down to one tiny spot on a diamond-cut, highly pure copper plate. That's where every X-ray laser pulse at SLAC's Linac Coherent Light Source gets its start. That tiny spot must be close to perfect or it can impair and even halt LCLS operations.

SLAC in May 2013 opened a new test facility at the Accelerator Structure Test Area (ASTA) to study the complex physics and chemistry that cause that shiny copper slab, called a cathode, to degrade over time, and to identify ways to maintain and improve its performance.

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.

SLAC's X-ray Laser Explores Big Data Frontier

It's no surprise that the data systems for SLAC's Linac Coherent Light Source X-ray laser have drawn heavily on the expertise of the particle physics community, where collecting and analyzing massive amounts of data are key to scientific success.

With its detectors collecting information on atomic- and molecular-scale phenomena measured in quadrillionths of a second, LCLS stores data at a rate and scale comparable to experiments at the world's most powerful particle collider, the Large Hadron Collider in Europe.
