The Advanced Light Source


The Advanced Light Source (ALS) is a third-generation synchrotron source at the Lawrence Berkeley National Laboratory, which operates the ALS as a U.S. Department of Energy national user facility open to scientists from academic, industrial, or government laboratories who submit peer-reviewed proposals. Based on a 1.9-GeV, low-emittance storage ring with long straight sections for insertion devices, the ALS is optimized for the highest brightness in the soft x-ray and vacuum ultraviolet spectral regions from undulator sources. Owing to the high brightness, which translates into a high flux of useful photons onto samples, the ALS is also a world-class source of shorter wavelength "intermediate-energy" x rays with both wiggler and bend-magnet sources. Infrared is also available from some bend-magnet ports.
