Advanced Photon Source | Argonne National Laboratory

The Advanced Photon Source (APS) at Argonne National Laboratory is a national synchrotron x-ray research facility funded by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences. The APS provides the brightest x-ray beams in the Western Hemisphere to more than 5,000 scientists worldwide.

ANNOUNCEMENTS:

Using temperatures approaching those found on the surface of the sun and intense x-ray beams from two synchrotron x-ray facilities, including the Advanced Photon Source at Argonne National Laboratory, researchers have observed liquids separating into two different states – one lighter and more perfect than the other – the first time the phenomenon has been seen in any liquid at any temperature. The researchers expect this discovery to have profound implications for gaining a greater understanding of liquids.

A New Spin on Inducing Chirality in Pre-biological Molecules

October 23, 2008

Researchers using an x-ray beamline at the U.S. Department of Energy’s Advanced Photon Source demonstrated that a previously unconsidered mechanism can play a role in chiral-selective chemistry: namely low-energy spin-polarized secondary electrons, produced by irradiation of a magnetic substrate.

How Ancient Rock Got Off to a Hot Start

October 22, 2008

A new technique that uses high-brightness x-ray beams at the Argonne Advanced Photon Source has enabled scientists to play “detective” and solve a debate about the origins of a three-billion-year-old fragment of magma, opening the door to the possibility of new discoveries about our planet's past.

A Virus That Can Infect Lung Cancer Cells

October 21, 2008

The structure of a virus that is harmless to normal human cells but an enemy of certain cancer cells has been determined by researchers using the U.S. Department of Energy’s Advanced Photon Source at Argonne National Laboratory. This new knowledge may help drug designers tweak the pathogen enough so that it can attack other tumor subtypes.

A Quantum of Vibration in an Unexpected Place

October 21, 2008

Studies carried out at the Argonne Advanced Photon Source have confirmed a link between specific phonon modes in biological proteins and biological function, showing that the physical concept of phonons, when observed at the correct length scale, is useful in biology, too.

APS2020 Renewal Plan

The APS Renewal is the first component of a strategic plan that aims to provide our users with the best hard x-ray source in the nation, and beyond, by the year 2020.

SESAME and the APS: Opening Doors Helps the Light Shine In

September 16, 2008

As Guvenc Akgul goes about learning the finer points of x-ray spectroscopy from his colleagues at the U.S. Department of Energy’s Advanced Photon Source, he represents a bridge between countries that, while separated by culture, distance, or regional factionalism, can find common ground in science at synchrotron x-ray research facilities.
