Facilities
The UV ring has 19 beamlines, of which 13 are operational. The X-ray ring has 58 beamlines, of which 51 are operational. The beamlines are operated and funded in numerous ways. However, since the NSLS is a user facility, any scientist that submits a proposal may be granted beamtime after peer-review. There are two types of beamlines at the NSLS: Facility Beamlines (FBs), of which there are 18, and Participating Research Team (PRT) beamlines, which currently total 46. FBs are operated by the NSLS staff and reserve a minimum of 50 percent of their beamtime for users and PRT beamlines reserve 25 percent of their beamtime for users.
Each X-ray beamline has an endstation called a hutch. These are large enclosures made of radiation shielding materials, such as steel and leaded glass, to protect the users from the ionizing radiation of the beam. On the X-ray floor, many of the experiments conducted use techniques such as XRD, XAFS, DAFS (X-ray diffraction anomalous fine structure), WAXS, and SAXS.
On the VUV ring, the endstations are usually UHV (ultra high vacuum) chambers that are used to conduct experiments using XPS, UPS, LEEM and NEXAFS.
In some beamlines, there are other analytical tools used in conjunction with synchrotron radiation, such as a mass spectrometer, a high power laser, or a gas chromatography mass spectrometer. These techniques help supplement and better quantify the experiments carried out at the endstation.

Famous quotes containing the word facilities:
“I have always found that when men have exhausted their own resources, they fall back on “the intentions of the Creator.” But their platitudes have ceased to have any influence with those women who believe they have the same facilities for communication with the Divine mind as men have.”
—Elizabeth Cady Stanton (1815–1902)
“Marriage is good enough for the lower classes: they have facilities for desertion that are denied to us.”
—George Bernard Shaw (1856–1950)
