X-ray light sources and electron imaging

The 40-foot-long segment of the new superconducting accelerator arrived on January 19, 2018 after a cross-country trip from Fermilab.

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.

As members of the lab’s Computer Science Division, they develop the tools needed to handle ginormous data volumes produced by the next generation of scientific discovery machines.

Innovations at SLAC, including the world’s shortest X-ray flashes, ultra-high-speed pulse trains and smart computer controls, promise to take ultrafast X-ray science to a whole new level.

They created a comprehensive picture of how the same chemical processes that give these cathodes their high capacity are also linked to changes in atomic structure that sap performance.

Biochemical 'action shots' with SLAC’s X-ray laser could help scientists develop synthetic enzymes for medicine and answer fundamental questions about how enzymes change during chemical reactions.

In experiments with the lab’s ultrafast "electron camera," laser light hitting a material is almost completely converted into nuclear vibrations, which are key to switching a material’s properties on and off for future electronics and other applications.

Research with SLAC’s X-ray laser simulates what happens when a meteor hits Earth’s crust. The results suggest that scientists studying impact sites have been overestimating the sizes of the meteors that made them.

A new way to observe this deformation as it happens can help study a wide range of phenomena, from meteor impacts to high-performance ceramics used in armor, as well as how to protect spacecraft from high-speed dust impacts.

Effort to improve the next generation of gravitational wave detectors includes atomic studies of new and better coatings for LIGO’s mirrors at SSRL.

He is recognized for his numerous contributions to the advancement of accelerator physics, community service and education.
