NSLS-II Status Overview Steve Dierker Associate Laboratory Director for Light Sources NSLS-II Project Director Project Advisory Committee May 24, 2007
NSLS-II Conceptual Design Report • 2006 was a busy year • Five reviews, one workshop, four advisory committee meetings, and more than 75 visitors • Conceptual Design Report • More than 150 contributors from 17 different institutions
CD-1 Review – December, 2006 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 Response to recommendations resolved at DOE Mini-Review in Feb, 2007
Project Scope Accelerator Systems • Storage Ring • Linac and Booster Injection System Experimental Facilities • Suite of 6 initial beamlines and instruments Conventional Facilities • Improvements to Land • Ring Building • Operations Center and distributed Lab/Office Buildings • Utilities R&D • Advanced optics for achieving 1 nm and 0.1 meV • Nanopositioning and mirror metrology • Advanced insertion devices

Experimental Facilities • Goal: Provide a minimum suite of insertion device beamlines to meet physical science that both exploit the unique capabilities of the NSLS-II source and provide work horse instruments for large user capacity. • Strategy: Six ID Beamlines in project: • Inelastic x-ray scattering (0.1 meV) • Nanoprobe (1nm) • Soft x-ray coherent scattering and imaging • Hard x-ray coherent scattering and SAXS • Powder diffraction (damping wiggler source) • EXAFS (damping wiggler source) • Goal: Ensure significant capacity for NSLS-II at the commencement of operation • Strategy: Transfer ~ 20 NSLS BM beamlines to NSLS-II (early NSLS-II ops funding) • Goal: Rapid build-out of remaining ID beamlines • Strategy: Pursue MIE funding
Recent Accomplishments • Responded to CD-1 review & new funding profile with revised scope/cost/sched Jan-May • Completed two sessions of EVMS training for NSLS-II Staff Feb & April • Started regular meetings of Schedule Task Force March • Conducted NSLS-II Monthly Status meetings with BHSO & BES March & April • Held Radiological Safety Design Workshop March 27-28 • Approved Work Plans for FY07 April • Completed Stability Task Force meetings and Workshop April 18-20 • Completed Accelerator Systems Advisory Committee meeting April 23-24 • Finalized Lattice Design & Footprint May 4 • Completed Conventional Facilities Advisory Committee meeting May 8-9 • Completed Experimental Facilities Advisory Committee meeting May 10-11 • Finalizing cost negotiations with A/E in anticipation of PED funds May • BNL funded modular addition to Project Offices April-June
Staffing • Making good progress with staff additions • Ferdinand Willeke engaged w/ project to succeed Satoshi Ozaki • 10 days in Feb, 10 days in March, 11 days in April • Must be out of country now due to VISA issues • Will join project full-time in July • Interface Managers for ASD, CFD, and XFD all in place • Other recent hires: • QA Manager, IT Manager, many physicists, engineers, & designers (see org chart on next vg) • 29 open requisitions, 13 reqs in process – many candidates identified; interviews ongoing • Highest priorities: • Experimental Facilities Division Director • Asst. Director for Construction Management • Issue: • Some planned FY07 hiring will be deferred to FY08 due to funding limitations
NSLS-II R&D Program • Accelerator Systems • Girder Prototyping and Storage Ring Magnet Alignment • Uses existing very large assembly space in 902 (SMD) • Insertion Device Development Laboratory • Requires significant expansion of present NSLS capabilities • Will locate in Bldg 832 or Bldg 727. Delayed to next year due to funding limitations • Experimental Facilities • MBE/Deposition Lab • MBE system, UHV chambers, and associated characterization hardware, e.g. STM • Nano-positioning Lab • Testing of engineering concepts. Must be vibrationally quiet with small thermal enclosures. • Crystal Preparation facility • Crystal cutting, polishing, orienting and mounting. Required for MLL and 0.1 meV optics development • Wet Lab • Crystal etching, MLL etching, and kinoform work. Requires fume hood, chemical storage, etc. • X-ray reflectivity Lab • Crystal characterization, include rotating anode or tube source for Laue work and reflectivity meas. • Optics Metrology Lab • Next gen LTP and ancillary equipment. Requires large, clean, and thermally isolated space.
Magnet Alignment R&D – Bldg 902 (SMD) Wire Mover • Magnets will be setup will be on an existing 15 ft. granite surface plate. • The wire movers will be mounted on two small separate granite surface plates on either side of the magnet setup. • The wire movers will be 22 ft. apart. • SLS magnets are on site. Design work to mount them on magnet positioners will begin soon.

ES&H Status • ES&H Plan and ES&H Policy have been issued • ES&H operating procedures and requirements from NSLS are being migrated to the Directorate Level to ensure uniform approach at both NSLS and NSLS-II • e.g.: Work Planning and Control Procedures, EMS/OHSAS Manuals, etc • All on-going work activities being performed for NSLS-II have been reviewed to make sure that program requirements are in place • ESH Assessments of design and operation on-going as design progresses
Preliminary Cost Estimate ($M) Cost Range $750M to $900M
Preliminary Funding Profile ($M) • FY09 Start Construction • Nov 2007 baseline validation planned to support FY09 budget request

Upcoming Events in 2007 • CD-1 ESAAB June 22 • User Workshop July 17-18 • EVMS Review and Certification Aug 13-16 • Final Review of NSLS-II CD-2 Performance Baseline Sep 21 • Conventional Facilities Advisory Committee Sep 25-26 • Experimental Facilities Advisory Committee Oct 4-5 • Accelerator Systems Advisory Committee Oct 8-9 • SC Independent Project Review/External Independent • Review for CD-2 Nov 6-9
Summary/Issues • Recent design changes provide greater flexibility • External booster, three pole wigglers, extra-long straight upgrade (Willeke) • Recent scope changes provide greater capability • Additional project beamlines, expansion of LOBs • Careful considerations have kept cost & schedule under control • Good progress at resolving design challenges • Stability requirements, heat load on front-ends • Making progress at developing R&D facilities and staff • Issue: Activity reduced or delayed till next year due to FY07 funding shortfall • Good relationships with BNL, BHSO, and BES • Open and transparent, focused on finding and supporting solutions
Charge to Committee • Is the facility design optimized to achieve the project goals? • Are the beamline development plans reasonable? • Is the organization appropriate for this stage of the project? • Does the revised funding profile appear to be consistent with the schedule goals? Is the slightly back loaded contingency profile reasonable? • Are there any concerns with the Preliminary PEP, e.g., are the definitions of CD-4a and CD-4b reasonable? • Are there suggestions on managing the transition to operations? • Are the plans for office, production, and R&D space reasonable for the construction period? Is the space plan for operations reasonable? • Are there things we should be doing to communicate the project status and issues both internally to NSLS-II staff and externally to stakeholders?
