The NSLS-II facility is designed to accommodate approximately 60 beamlines, supporting over 3,000 users. Key features include various types of straight sections for user undulators, damping wigglers, and numerous beamline ports dedicated to UV, soft X-ray, mid-IR, and far-IR studies. Conceptual designs exist for inelastic X-ray scattering, nanoprobe applications, protein crystallography, and more. A phased construction schedule is laid out, with initial commissioning aimed for 2013, ensuring a wide range of advanced experimental capabilities for the scientific community.

  2. 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)

  4. 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

  10. 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)

  11. 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.
