The National Synchrotron Light Source is a state-of-the-art, medium-energy (3-billion-electron-volt, or GeV) electron storage ring that produces x-rays up to 10,000 times brighter than the NSLS. The mission of the National Synchrotron Light Source is to provide extremely bright x-rays for basic and applied research in biology and medicine, materials and chemical sciences, geosciences and environmental sciences, and nanoscience. To support this program, the NSLS-II must design, fabricate, assemble, test, install, and operate unique research equipment to generate, transport, transfer, accelerate and focus electron and X-ray beams. This includes a combination of custom designed and built parts and vendor produced components developed by a collaboration of the
