NNSA Administrator visits Brookhaven National Laboratory

On Friday, May 6, DOE Under Secretary for Nuclear Security and NNSA Administrator Lt. Gen. Frank G. Klotz (Ret.) visited Brookhaven National Laboratory in Upton, New York. Brookhaven Lab brings world-class facilities and expertise to the most exciting and important questions in basic and applied science—from the birth of the universe to the sustainable energy technology of tomorrow.

NNSA Administrator Frank Klotz speaks with Juergen Thieme, Group Leader of the Submicron Resolution X-ray Spectroscopy Beamline (SRX) at Brookhaven’s National Synchrotron Light Source II (NSLS-II). SRX hosts scientific users from around the world who conduct research in environmental sciences, life sciences, and material sciences. SRX offers world-leading imaging capabilities, helping researchers understand complex natural and engineered systems from the micron to nanometer scale.

Focusing the beam to that level allows researchers to see the structures on that tiny length scale, whether they are proteins in a biological sample or the inner workings of a fuel cell catalyst. The combination of the unique detection capabilities of X-rays and the unprecedented resolution of this beamline will be critical for studies in many areas of science and technology.
