The National Synchrotron Light Source II (NSLS-II) at Brookhaven National Laboratory (BNL) in Upton, New York is a national user research facility funded primarily by the U.S. Department of Energy's (DOE) Office of Science. NSLS-II is a synchrotron light source, designed to produce X-rays 10,000 times brighter than BNL's original light source, the National Synchrotron Light Source (NSLS). NSLS-II supports research in energy security, advanced materials synthesis and manufacturing, environment, and human health.
