  1. NSLS-II Project Overview Steve Dierker Associate Laboratory Director for Light Sources NSLS-II Project Director Experimental Facilities Advisory Committee May 10, 2007

  2. 2006 was a busy year… NSLS-II Project Organization • Created – January Five Reviews • Lattice and Accelerator Configuration Review – May 11-12 • DOE Review – May 16 • Cost Review – June 13 • DOE Review – July 18 • DOE Review – December 12-14 One Workshop • Acquisition Strategy Workshop (co-sponsored with SC) – June 20-21 Four Advisory Committee Meetings • Held all four NSLS-II advisory committee meetings in October Hosted more than 75 Visitors • CDR A/E on board and A/E held several programming meetings Conceptual Design Completed • More than 150 contributors from 17 different institutions • Special site studies (Geotechnical, RFI, Vibration) • Constructability review & independent cost estimate for conventional facilities • Detailed project cost estimate & refined project WBS • Environmental Assessment completed; FONSI approved by BHSO • Required documents (AS, PPEP, ESH, QA, RM, PHA) all complete

  3. NSLS-II Conceptual Design Report

  4. NSLS-II Project ScopePresented at CD-1 Review Accelerator Systems • Storage Ring • Linac and Booster Injection System Experimental Facilities • Suite of ~ 5 initial beamlines and instruments Conventional Facilities • Improvements to Land • Ring Building • Central and distributed Lab/Office Buildings • Utilities • R&D • Advanced optics for achieving 1 nm and 0.1 meV • Advanced insertion devices

  5. NSLS-II Storage Ring Performance • Very Broad Spectral coverage • IR through very hard x-rays • Brightness exceeds any other synchrotron from 10 eV to 20 keV • > 1021 p/s/0.1%/mm2/mrad2 from ~ 2 keV to ~ 10 keV • Flux exceeds any other synchrotron from 10 eV to 20 keV • > 1016 ph/s/0.1%bw from ~ 500 eV to ~ 10 keV • Smallest beam size of any synchrotron: • sy = 3.1 mm, sx = 38.5 mm • s’y = 1.8 mrad, s’x = 18.2 mrad • Top-off Operation • Current stability better than 1% • Accommodates 27 user insertion devices (8 m and 5 m) and 30 BM beamlines • X-ray Ring • 3 GeV, 500 mA, top-off injection • Circumference 780 m • 30 cell, Double Bend Achromat • Novel design featuring damping wigglers and soft bend magnets • Ultra-low emittance (ex, ey) 0.5, 0.008 nm-rad • (Diffraction limited in vertical at 10 keV) • Pulse Length (rms) 15 psec

  7. CD-1 Review Overall, successful and very positive regarding design and team Principle Recommendations: • Consider moving booster outside of storage ring tunnel • Consider use of NC RF instead of SC RF • Increase the scope of the Experimental Facilities portion of the project to provide a minimal suite of beamlines which both exploit the unique capabilities of the NSLS-II source and meet the scientific needs of the NSLS user community • R&D program is appropriate but expand to include mirror metrology • Develop a policy whereby the design, construction, and operation of all beamlines, both DOE funded as well as non-DOE funded, will be the responsibility of the Experimental Facilities staff • Increase cost range to $750M - $900M

  8. Revised NSLS-II Site Plan NSLS LOB JPSI LOB CFN Storage Ring Booster Linac LOB LOB LOB 400 FEET 100 200 0

  9. Revised Building Program • Alternatives to CLOB were evaluated • Space in NSLS will be maximized for NSLS-II administrative and technical support functions • Only functions in direct support of NSLS-II facility and accelerator operations will be housed at NSLS-II • Operations Center (OC) • Lab/office Buildings (LOBs) • OC will include: • Control room, computer room, Ctrl rm Conference & break room, operations supervisory offices • Entry foyer, viewing gallery and access bridge to electrical mezzanine and control room area • All of these spaces (and more) were previously included in the CLOB

  10. Project Beamlines • A minimum suite of insertion device beamlines to meet physical science needs has been identified. These take advantage of the unique source properties of NSLS-II and also provide work horse instruments for large user capacity • Recommended beamlines: • Nanoprobe (1nm) • Inelastic x-ray scattering (0.1 meV) • Soft x-ray coherent scattering and imaging • Hard x-ray coherent scattering and SAXS • Powder diffraction (damping wiggler source) • EXAFS (damping wiggler source)

  11. Transitioning to Operations • A phased transition to NSLS-II operations is planned: • CD-4a – Initial Operations • Beneficial Occupancy of Experimental Floor • Initial limited storage ring operations and limited user operations during installation and commissioning of beamlines • CD-4b – Start of Operations • All commissioning goals have been achieved • Transitioning from NSLS to NSLS-II • Important to begin this transition as early as possible • Continue operations of NSLS until NSLS-II operational (CD-4b) • Move NSLS programs to NSLS-II between CD-4a and CD-4b • NSLS and NSLS-II staff merge to operate NSLS-II

  12. NSLS Beamline Transfer Plan • Evaluated NSLS beamlinesin terms of technical suitability for moving to a soft bend, a 3PW, or an insertion device at NSLS-II • Estimated moving costs and costs for upgrading to be suitable for NSLS-II • The productivity (number of publications and premier publications) and user demand (hours requested) of the existing NSLS beamlines were evaluated • From this list, and the technical and cost considerations, about 20 bending magnet beamlines were identified that would support the largest number of users with the greatest scientific impact, covering the following techniques: • EXAFS, SAXS, powder diffraction, scattering, PX, imaging, microdiffraction, topography, far-IR spectroscopy. • Estimate that these could accommodate at least 1300 users/yr • Plan to begin transferring these to NSLS-II at CD-4a • Assume that NSLS-II operations funding starts at CD-4a and covers transfer of selected NSLS beamlines to the new NSLS-II facility as well as initial storage ring operations
