The National Synchrotron Light Source II, or NSLS-II, is being constructed at Brookhaven National Laboratory in New York. It will cost US$912,000,000.[1] The NSLS-II will replace the current NSLS. Construction of NSLS-II began in 2009 and operations are expected in 2015.[4] NSLS-II will be a new state-of-the-art, medium-energy electron storage ring operating at 3 GeV. It is designed to produce x-rays more than 10,000 times brighter than the current NSLS.[4]
Project
The NSLS-II storage ring is 792 m in length[5] and there will be 60 to 80 beamlines.[6] NSLS-II is designed to deliver photons with high average spectral brightness in the 2 keV to 10 keV energy range exceeding 1021 ph/s/0.1%BW/mm2/mrad2.[5] The spectral flux density should exceed 1015 ph/s/0.1%BW in all spectral ranges.[5] This is considered cutting-edge performance and requires the storage ring to support a very high-current electron beam of 500 mA. The ring will operate at 3 GeV, which is considered medium range, yet the brightness and flux are what will make NSLS-II unique.
