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.

A New Way to Tune Emergent Magnetism

Perpendicular magnetic anisotropy (PMA)—where magnetic moments in a thin film preferentially point out of the plane of the film—is an emergent phenomenon of both fundamental and technological interest. A combination of x-ray techniques demonstrate how to tune PMA in transition-metal oxide multilayers. ... Read more »

X-Rays Provide Key Insights on Path to Lithium-Rich Battery Electrode

If you add more lithium to the positive electrode of a lithium-ion battery, it can store much more charge in the same amount of space, theoretically powering an electric car 30 to 50 percent farther between charges. But these lithium-rich cathodes quickly lose voltage, and years of research have not been able to pin down why—until now. ... Read more »

Studying Gas Mask Filters So People Can Breathe Easier

Scientists have put the x-ray spotlight on composite materials in respirators used by the military, police, and first responders. The results provide reassuring news about the effectiveness of current filters and provide fundamental information that could lead to more advanced gas masks as well as protective gear for civilian applications. ...

ALS Director Roger Falcone Says Farewell

When I joined the Advanced Light Source 11 years ago, I came with limited understanding of ALS, but with great respect and admiration for both the facility and its staff from my time as a user. I wanted to learn and see how I could help, and it has been a wonderful experience. ... Read more »

Dmitriy Voronov Receives Klaus Halbach Award

The 2017 Klaus Halbach Award for Innovative Instrumentation at the ALS was recently awarded to ALS Staff Scientist Dmitriy Voronov “for pioneering work in the area of advanced x-ray gratings.” The research that led up to Voronov’s award began about 10 years ago when he started at the ALS in the Experimental Systems Group with Howard Padmore. ...
