President Obama at the Advanced Photon Source

President Obama visited Argonne National Laboratory on Friday, March 15, 2013, where he “spoke inside a building housing a giant X-ray [machine] known as the Advanced Photon Source, described by Argonne officials as the brightest source of X-rays in the Western Hemisphere. The facility allows scientists to explore materials on a nanoscale and to study ways to improve engine combustion,” as described in a story that appeared in the New York Times, which can be read here.

An article and video of the President’s visit can be found on the Argonne Web site.

Argonne photos of the visit are on the Laboratory’s Flickr page here.

Extensive links to media coverage of the visit have been compiled on this Argonne Web page.

The Advanced Photon Source at Argonne National Laboratory is one of five national synchrotron radiation light sources supported by the U.S. Department of Energy’s Office of Science to carry out applied and basic research to understand, predict, and ultimately control matter and energy at the electronic, atomic, and molecular levels, provide the foundations for new energy technologies, and support DOE missions in energy, environment, and national security.

Argonne National Laboratory seeks solutions to pressing national problems in science and technology. The nation's first national laboratory, Argonne conducts leading-edge basic and applied scientific research in virtually every scientific discipline. Argonne researchers work closely with researchers from hundreds of companies, universities, and federal, state and municipal agencies to help them solve their specific problems, advance America's scientific leadership and prepare the nation for a better future. With employees from more than 60 nations, Argonne is managed by UChicago Argonne, LLC for the U.S. Department of Energy's Office of Science.
