6. Major Design Issues Injector Re-design based on compact booster concept performed Route: semi turn-key procurement Concern: high cost and single vendor Action: explore alternative vendors Reducing Lattice Complexity in order to reduce cost and free up space Present Status: 2 chromatic sextupole families, triplet focusing for matching the ID straights Action: perform comprehensive simulation study, keep reserve to introduce more sextupoles or other multipoles Design Magnet Support System: (a) align magnets to < 30 mm (b) suppresses girder amplification of vibrations < 50Hz (c) insensitive to temperature changes Present Status: Existence proof of (a) further studies planned

7. Stretched Wire Test Measurements • High precision magnet alignment procedure using a vibrating wire technique • Existence proof for 30micron alignment tolerances achieved with this method at Cornell • Magnet alignment precision of < 10 mm demonstrated recently at BNL See Satoshi Ozaki’s presentation in acc. b.o.

9. Scope Contingency

10. Estimated Cost Profile These are burdened and escalated numbers More detailed information in accelerator breakout

11. Accelerator Cost Accelerator Systems, Accelerator Systems R&D, Accelerator Systems Pre-Ops ~ 250 WBS items level 3-6 1200 scheduled activities

12. Detailed Cost Information LEVEL 2 LEVEL 3 LEVEL 4 Activities LEVEL 5

13. Areas of Risk • Cost Risks: - Turn key procurements of LINAC, RF Cavities, RF transmitter are subject to currency exchange rate changes, partially only single vendors - Procurement of high quality permanent magnet material in view of recent large price increases) Mitigation: allocation of contingency • Schedule and Cost Risk Only one, at most 2 vendors for SC cavities, LINAC Mitigation: Efforts to validate more vendors • Schedule, Cost Risk, Technical Risk - Copy of existing Landau cavity design, need complicated collaboration Mitigation: In-house development under consideration - Low beam lifetime due to low D.A. Mitigation: Landau Cavity provides margin, additional sextupole circuits require contingency • Technical & Schedule Risk: Meeting requirements in Beam Stability, high precision alignment Mitigation: Mitigation: problems addressed in R&D program

14. Total Estimated Cost and Bottoms –Up Contingency Assessment WBS Dictionary: Design and develop the NSLS-II accelerator systems: storage ring, injector complex, insertion devices, and accelerator infrastructure, including controls. Additional activities include the detailed design of corresponding components and subsystems; their procurement, testing, and assembly; and, finally, installation of the entire accelerator complex for NSLS-II. *) *) margin taken into account in cost estimate

15. Scheduling • Weekly meetings Febr.-March 07 of technical staff with project support team to: • Agree on global schedule strategy, • Define milestones, • Acknowledge constraints, • Envision build-in float • Introduce integrated testing at the end of the installation • Acknowledge installation as the most complicated schedule activity, • generate very detailed installation work break-down and sequencing • Agree on pentant-wise staged installation while the building is being completed • Generate a logical network which link the schedule activities • Detailed assessment of labor work out duration of activities as part of the cost estimate in July 07, consolidation in August 07 • Generating a schedule • using the available float to support procurement strategies and • to match the funding profile, • very close and intense collaboration between technical staff and project support team in September 07 • Reiterate schedule to optimize TPC, staffing profile, procurement strategies

16. Accelerator Systems Schedule • Booster on the critical path • Reason: • Injector Turn-key procurements delayed to preserve option for alternative vendor development of change of procurement plan as part of the injector risk mitigation strategy • It also helps to match the time phased cost estimate with the funding profile • After May 2013: Accelerator and ID commissioning

17. Critical Path | FY09 | FY10 | FY11 | FY12 | FY13 | FY14 | FY15 | Booster on the critical path April 09 – May 2013 Reason: Injector Turn-key procurements delayed to preserve option for alternative vendor development of change of procurement plan as part of the injector risk mitigation strategy It also helps to match the time phased cost estimate with the funding profile After May 2013: Accelerator commissioning and ID comm.

18. Estimated Labor • Accelerator Systems Staffing • Planned labor will allow for a smooth staffing plan. • Detailed Staffing plans have been developed based on estimated labor effort • Peak work loads in FY12 need temporary labor

19. Labor Type Staffing Profile Total 575 FTE includes 1.03 1.02.01 & 1.06.02 20 FTE temp. M/E Techs in FY 12 Mech. Designers move to EF in FY11 Assume transition to operations Smooth labor profile

24. Summary • Design of Accelerator Systems has advanced well, in some area’s design is close to be completed, in other areas design process is stretched out in time to optimize cost distribution • A detailed and thorough cost estimate has been produced for NSLS-II accelerator systems which is based on fairly detailed design • The schedule has been generated based on detailed planning which involved the entire high level technical staff of the division and based on the detailed cost estimate • Based on time phased cost estimate a firm staffing plan has been developed so that hirings can start now to assure execution of the project as planned • Major risks have been identified and mitigation plans have been developed • All these constitute a reliable base for the project baseline • An organizational structure is envisioned which consists of a stable line management structure and dynamic task forces which will address special project needs • NSLS-II Accelerator Systems ready to move to detailed engineering phase
