Berkeley Lab
Bringing Science Solutions to the World

ALS COVID status update. Visit this link for user-related information. See here for staff-only information.

The Advanced Light Source is a U.S. Department of Energy scientific user facility at Lawrence Berkeley National Laboratory. Our mission is to advance science for the benefit of society by providing our world-class synchrotron light source capabilities and expertise to a broad scientific community.


March 3 Deadline for General User Proposals

The User Office is accepting new General User Proposals (GUPs) from scientists who wish to conduct research at the ALS in the 2021-2 (August–December) cycle. The deadline for submissions is March 3, 2021.Details

2D MXene Shows Evidence of a Magnetic Transition

A variety of experiments, including ALS x-ray studies, provided direct evidence of a magnetic transition in a 2D compound called a MXene (pronounced “maxene”). The finding adds new functionality to a family of materials with numerous ways to fine-tune properties for applications ranging from spintronic devices to electromagnetic shielding.

A Detailed Look Inside Tsetse Flies

To better understand the unique reproductive biology of tsetse flies, which are carriers of the parasites that cause a deadly infection known as African sleeping sickness, researchers explored the intact organs and tissues of tsetse flies using a powerful 3D x-ray imaging technique at Berkeley Lab’s Advanced Light Source.

Materials from Town Hall on Shutdown Schedules Now Available

On January 26, the ALS held a town hall on the schedule for upcoming long shutdowns. The event provided up-to-date information on the schedule, explained the motivations behind decisions, and discussed principles and strategies for future decision-making. Slides and a recording from the event, as well as an FAQs document, are posted to the ALS website. Read more »

Johanna Nelson Weker, Users’ Executive Committee Chair

This year’s Users’ Executive Committee chair first used synchrotrons as a grad student and loved the experience so much she eventually became a beamline scientist at SSRL. She’s excited to work closely with the user community during the ALS Upgrade and is well versed in post-beamtime food options in Berkeley. Read more »

Stacking the Deck for Custom-Built Hybrid Materials

Researchers fabricated an electronically coupled heterostructure from a novel semiconducting 2D polymer and a 2D transition metal dichalcogenide. Dramatic optical and electronic changes emerged as polymer thickness decreased, underscoring the potential for the discovery of emergent phenomena in studies of hybrid heterostructures. Read more »
