ALS

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.

Toward Control of Spin States for Molecular Electronics

Researchers demonstrated, via x-ray absorption spectroscopy, that a molecule’s spin state can be reversibly switched at constant room temperature by magnetism. The results represent a major step toward the goal of programmable, nanoscale molecular electronics for high-speed, low-power, logic and memory applications. Read more »

Imaging Magnetic Microstructure Response to Substrate Strain

A ferromagnetic thin film on a piezoelectric substrate offers a way to control magnetization in ultralow-power devices by relying on coupling between the piezoelectric and ferromagnetic components. At the ALS, researchers were able to image the electrically induced magnetic behavior and correlate it with the piezo-strain driving it. Read more »

Kevan Anderson, Beamline Controls Lead

Kevan Anderson joined the ALS in August as supervisor of the Beamline Controls Group, which is responsible for supporting the integrated control systems associated with ALS beamlines. Anderson works with a group of software developers who are available to beamline scientists. Read more »

TE Connectivity Uses ALS to Improve Conductive Plastics

TE Connectivity used ALS microtomography capabilities to optimize the material and manufacturing parameters of their conductive plastics to impart good electrical conductivity. Conductive plastics with good electrical properties offer processing and cost benefits over metal alternatives, with applications ranging from automotive to data communications. Read more »
