3 BROOKHAVEN SCIENCE ASSOCIATES Design Specifications Ultra-high brightness -Drives emittance, energy spread, stability. High flux -Drives current, top-up, length of straight sections. Wide spectral range: 0.1 meV to 100 keV -Drives user devices (BM, undulators, SCW), storage ring energy. Experimental View:

14 BROOKHAVEN SCIENCE ASSOCIATES Beamlines BROOKHAVEN SCIENCE ASSOCIATES For the purposes of obtaining a detailed cost estimate and to explore the technical issues for state-of-the-art beamlines at NSLS-II, Five insertion device beamlines were explored in some detail: 1)Inelastic X-ray Scattering (Hill, Shvyd’ko and Baron) 2)Hard X-ray Nanoprobe (Gog, Evans-Lutterodt) 3)Hard X-ray Coherent Scattering (Sandy, Mochrie, Robinson) 4)Soft x-ray Imaging and Coherent scattering (Sanchez-Hanke, Hulbert, Reinginer) 5)Soft x-ray resonant scattering and inelastic scattering (Arena, Hulbert, Reinginer)

15 BROOKHAVEN SCIENCE ASSOCIATES Beamlines Superconducting Magnet NSLS II Experimental floor In addition, we have considered a number of other beamlines at a less detailed level: High magnetic field (Nelson) High Energy (Zhong) SAXS (Yang) IR (Carr) Imaging (Shen) Damping Wigglers (Berman) PX (Berman) ARPES (Johnson/Vescovo) Bending Magnet (Berman/Arena)

16 BROOKHAVEN SCIENCE ASSOCIATES Beamline Development Beamline Access Teams (BATs) Facility receives funding to design, construct, and operate beamlines. Beamline Development Teams (BDTs) User group receives funding to design, construct, and operate beamline. Two principal modes : User groups would form and work with the facility to define the scientific mission and technical requirements for the beamline

In this scenario a few IDs and a few BMs remain open.

22 BROOKHAVEN SCIENCE ASSOCIATES Summary XFD portion of CDR is nearing completion. User requirements generated by this have driven accelerator and conventional facilities design. 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. Some beamlines will be built as part of the construction project utilizing a trust fund approach. These will begin commissioning in Remaining beamlines will be built with other funds (e.g. will pursue potential MIEs and other non-BES funds) and brought online in the following years. Items requiring R+D have been identified and a plan outlined. User Access modes and facility build-out issues have begun to be addressed.
