The Advanced Light Source is a Department of Energy-funded synchrotron facility that provides users from around the world access to the brightest beams of soft x-rays, together with hard x-rays and infrared, for scientific research and technology development in a wide range of disciplines.

Strain Turns Tin into a 3D Topological Dirac Semimetal

A small amount of compressive strain turns a nonmetallic form of tin into a topological Dirac semimetal—a kind of “supermetal” with very high electron mobility. With its rich topological phase diagram, the material shows promise for both novel physics and eventual device applications. ... Read more »

New Insights into Nanoscale Deformation

A group of scientists used Laue x-ray microdiffraction at the ALS to probe plastic deformation mechanisms at the nanoscale. Their findings may overturn conventional theory and reshape our understanding of the mechanical behavior of a host of nanocrystalline metals. ... Read more »

Tribute to E.O. Lawrence Moves into ALS Lobby

There’s some new artwork gracing the ALS lobby—a stately portrait of Berkeley Lab founder Ernest Orlando Lawrence. The painting has a deep connection to the Lab, and so does the artist. He was a longtime Berkeley Lab employee and the father of Berkeley Lab Mechanical Technician Jim Dougherty, who frequently works on the undulators at the ALS. ... Read more »
