Berkeley Lab
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.

Modulating Infrared Light with 2D Black Phosphorus

Two-dimensional materials represent a promising new frontier in the field of optoelectronics. Most progress so far, however, has been in the visible-light range. Now, at the ALS, researchers have measured the infrared transmission spectra of ultrathin samples of black phosphorus under an applied electric field. ... Read more »


UEC Update

The ALS Users' Executive Committee met in mid-March. Topics of discussion included this year's User Meeting and possible combined projects with the Molecular Foundry UEC. Users should mark their calendars for the next User Forum, to be held June 1 at 3:30 p.m. User Forums are an opportunity for users to learn about UEC activities and to bring up questions and concerns.

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 »

COSMIC Achieves First Light

On Wednesday, March 29, the COherent Scattering and MICroscopy (COSMIC) Beamline (7.0.1) achieved first light, a significant milestone in the ALS’s plans to capitalize on recent gains in soft x-ray coherence provided by modern storage-ring light sources. ... Read more »

2017 ALS Shutdown Recap

The last few months were quieter than usual for ALS users but not for staff tasked with maintaining and improving the ALS. The recent ALS shutdown was one of the longest on record, spanning almost three months. Those involved say it was also one of the most successful, with everything on the to-do list crossed off. The work accomplished paves the way for new beamlines, better water-cooling capacity, and ALS-U.
