The NSLS-II storage ring is 792 m in length 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. The ring will operate at 3 GeV, which is considered medium range, yet the brightness and flux are what will make NSLS-II unique.

The three-pole wigglers, are inserted just upstream of the downstream bend magnet in the super-period, will produce a very useful hard x-ray bend-magnet-like spectrum. With a critical energy of 6 keV, the three-pole wigglers will produce usable hard x-ray flux out to ~25 keV. The emitted horizontal angular fan from these devices is 2 mrad wide.
