User Resources for NSLS-II operations and experiments during COVID-19

National Synchrotron Light Source II

NSLS-II is a state-of-the-art 3 GeV electron storage ring. The facility offers scientific and industrial researchers an array of beamlines with x-ray, ultraviolet, and infrared light to enable discoveries in clean and affordable energy, high-temperature superconductivity, molecular electronics, and more. Overview »


The next deadline for NSLS-II beam time proposals and beam time requests is January 31, 2021.  |   Submission Details

Beamlines at the National Synchrotron Light Source II are open to academic and industrial users for scientific research. All research proposals are subjected to peer review and ranked against competing proposals based on scientific merit.

NSLS-II Beamlines

NSLS-II’s beamlines and experimental stations offer unique, cutting-edge research tools for a wide variety of scientific areas. All beamlines are organized into five science programs, based on the research capabilities and expertise they offer.

    NSLS-II Friday Lunchtime Seminar

    "Local structural symmetry breaking at ambient conditions in FeSe superconductor"

    Presented by Robert Koch, Condensed Matter Physics and Materials Science Dept

    12 pm, ZoomGov

    Friday, October 23, 2020, 12:00 pm

    Hosted by: Ignace Jarrige

    We report pair distribution function measurements of the iron-based superconductor FeSe above and below the structural transition temperature. Structural analysis reveals a local orthorhombic distortion with a correlation length of about 4 nm at temperatures where an average tetragonal symmetry is observed. The analysis further demonstrates that the local distortion is larger than the global distortion at temperatures where the average observed symmetry is orthorhombic. Our results suggest that the low-temperature macroscopic nematic state in FeSe forms from an imperfect ordering of orbital-degeneracy-lifted nematic fluctuations which persist up to at least 300 K.

  2. OCT



    Virtual Symposium

    "National Virtual Biotechnology Laboratory Symposium"

    11:30 am, Virtual - Registration required

    Wednesday, October 28, 2020, 11:30 am

    Hosted by: John Hill

    The symposium is a virtual event to highlight the impact the U.S. Department of Energy's (DOE) National Virtual Biotechnology Laboratory (NVBL) has had utilizing the unique capabilities of the DOE to tackle the science and technology challenges associated with COVID-19, and to discuss areas in which the NVBL can have impact in the future. With perspectives from Chris Fall, Director, Office of Science, DOE, and William A. Bookless, Principal Deputy Administrator of the National Nuclear Security Administration, the event will feature presentations from lead investigators reporting progress in: • Epidemiological modeling • Therapeutics • Testing • Understanding transport of the virus • Solving issues around supply chain challenges In addition, keynote speakers from outside the NVBL will discuss the upcoming science and technology needs in computing, testing and surveillance, and vaccines.
