NSLS-II Beamlines • 15 five m straights for user undulators • Could potentially drive up to 30 beamlines by canting two undulators • 4 eight m straights for user undulators • Could potentially drive up to 12 beamlines by canting three undulators • 8 eight m straights for user damping wigglers • Could potentially drive up to 24 beamlines by canting three DWs • 20 BM ports for UV and soft X-rays • 10 BM ports for IR • 5 large aperture for far-IR • 5 regular aperture for mid/near-IR At least 57 beamlines Many more w/ mulitple IDs per straight (plus possible multiple hutches per beamline)

Beamlines • Conceptual or pre-conceptual designs exist for a number of beamlines: • Inelastic X-ray Scattering • Nanoprobe • Hard x-ray Coherent scattering • Soft x-ray Imaging and coherent scattering • Soft x-ray resonant elastic and inelastic scattering • High magnetic field • High Energy • Small Angle X-ray Scattering • Infra-Red • Imaging • Damping Wigglers • Protein Crystallography • Electron Spectroscopy • Bending Magnet Superconducting Magnet NSLS II Experimental floor

Noise and Stability • One issue users care a lot about is noise: • Mechanical • Isolate sources of noise • Pay attention to vibration damping (thick slab) • Electrical • Clean (conditioned) power • Dirty power • High quality grounds for each • RFI • Shield NEXRAD • Shield local sources (Storage Ring RF cavities)
Summary • Facility will ultimately support ~60+ beamlines and >3000 users. • Conceptual designs have been carried out for a number of beamlines to inform a detailed cost estimate, and a number of others at a pre-conceptual level. • A small number of beamlines will be built as part of the construction project utilizing a trust fund approach. These will begin commissioning in 2013. • Remaining beamlines will be built with other funds (MIE and other non-BES funds) and brought online in the following years.
