About the National Synchrotron Light Source II

From batteries and microelectronics to drug design and cultural heritage, scientists advance our understanding of many materials every day to solve the world’s greatest challenges. However, today's problems are so complex that they require scientists to study materials with highly specialized tools and expertise that are not readily available at most institutions.

That’s where the National Synchrotron Light Source II (NSLS-II) comes in. As one of the newest, most advanced synchrotron facilities in the world, NSLS-II enables its growing research community to study materials with nanoscale resolution and exquisite sensitivity by providing cutting-edge capabilities.

The facility’s state-of-the-art, medium-energy electron storage ring (3 billion electron-volts) generates ultrabright, highly stable beams of light, ranging from infrared to hard x-rays, to run 29 experimental stations, or beamlines. Each of our beamlines offers unique research tools to reveal the electronic, chemical, and atomic structure of materials.

Together with visiting researchers (users) and partners from all around the world, interdisciplinary teams at NSLS-II explore materials, focus on the most important challenges in science and technology. Learn more about this U.S. Department of Energy (DOE) Office of Science User Facility.
