National Synchrotron Light Source

The National Synchrotron Light Source at Brookhaven National Laboratory on Long Island, New York, was a major research facility that served as a source of synchrotron radiation. Operated by the U.S. Department of Energy, the facility had two electron storage rings: the VUV ring for infrared, visible, and ultraviolet light, and the X-Ray ring for X-rays. Both rings went into operation in the late 1980s. After they were shut down in 2014, the facility was replaced by its successor, NSLS-II, which had been under construction since 2009.
