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 »
NSLS users please note: The original National Synchrotron Light Source has permanently ceased operations. All future synchrotron studies at Brookhaven National Lab will be carried out at NSLS-II. Transition information.
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.
When fully built out, National Synchrotron Light Source II will accommodate approximately 60 to 70 beamlines. Thirty beamlines are currently in various stages of development and will provide significant research capacity in early operations.
