Advanced Light Source (ALS)

PROFILE als-cover-photo

The Advanced Light Source (ALS), located at Lawrence Berkeley National Laboratory, is a third-generation synchrotron 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. Funded by the Basic Energy Sciences program of the U.S. Department of Energy Office of Science, it welcomes researchers from academia, industry, and government.

  • The ALS hosts more than 2,000 users each year.
  • The ALS-U project, a planned upgrade of the ALS, will transform the facility into a fourth-generation storage-ring light source with unparalleled soft x-ray coherent flux, as well as excellent infrared, EUV, and hard x-ray capabilities.
