National Synchrotron Light Source II (NSLS-II)


The National Synchrotron Light Source II (NSLS-II) at Brookhaven National Laboratory is one of the newest, most advanced synchrotron facilities in the world and a U.S. Department of Energy (DOE) Office of Science User Facility.
NSLS-II is a state-of-the-art, medium-energy electron storage ring (3 billion electron-volts) with a highly stable electron beam. It is designed to deliver world-leading intensity and brightness and offers specialised in operando experimental conditions as well as multiscale and multimodal measurements allowing complex problems to be addressed with multiple techniques.
The facility opened its doors to researchers in 2015 and enables its user community to study materials with nanoscale resolution and exquisite sensitivity by providing cutting-edge capabilities for X-ray imaging and high-energy resolution analysis. Researchers from around the globe come to NSLS-II to focus on the most important challenges at the nanoscale in fields such as condensed matter and materials physics, chemistry, and biology.

    • The 27 state-of-the-art beamlines, with 2 more beamlines under construction offer unique, cutting-edge research tools from infrared light to hard X-rays.
    • Each year, more than 1000 researchers from universities, government laboratories, and companies use NSLS-II.
