During normal operations, the electrons in the storage rings lost energy and as such, the rings were re-injected every 12 (X-ray ring) and 4 (VUV ring) hours. The difference in time arose from the fact that VUV light has a larger wavelength and thus has lower energy which leads to faster decay, while

Ground was broken for the NSLS on
September 28, 1978. The VUV ring began operations in late 1982 and the X-ray ring was commissioned in 1984. In 1986, a second phase of construction expanded the NSLS by 52,000 square feet (4,800 m), which added offices, laboratories and room for new experimental

Beamlines (FBs), which were operated by the NSLS staff and reserved a minimum of 50 percent of their beamtime for users, and Participating Research Team (PRT) beamlines, which were operated and staffed by external groups and reserved at least 25 percent of their beamtime for users.
340:
The UV ring had 19 beamlines, while the X-ray ring had 58 beamlines. The beamlines were operated and funded in numerous ways. However, since the NSLS was a user facility, any scientist that submitted a proposal could be granted beamtime after peer-review. There were two types of beamlines at the

The VUV ring at the
National Synchrotron Light Source was one of the first of the 2nd generation light sources to operate in the world. It was initially designed in 1976 and commissioned in 1983. During the Phase II upgrade in 1986, two insertion wigglers/undulators were added to the VUV ring,
286:. The final lattice design was completed in 1978 and the first stored beam was obtained in September 1982. By 1985, the experimental program was in a rapid state of development, and by the end of 1990, the Phase II beamlines and insertion devices were brought into operation.
302:. Next, the electrons entered a booster ring, where their energy was increased to 750 MeV, and were then injected into either the VUV ring or the X-ray ring. In the VUV ring, the electrons were further ramped up to 825 MeV and electrons in the X-ray ring were ramped to 2.8

The
National Synchrotron Light Source hosted more than 2,200 users from 41 U.S. states and 30 other countries in 2009. In 2009, there were 658 journal publications and 764 total publications including journal publications, books, patents, thesis, and reports.
