4 BROOKHAVEN SCIENCE ASSOCIATES Possible Bending Magnet Usage at NSLS-II “ Beamline types ” in red are beamlines to be moved over from NSLS Note: there is not always a 1:1 correspondence with beamlines at NSLS and NSLS-II. In some cases, equipment may be taken from multiple beamlines.

5 BROOKHAVEN SCIENCE ASSOCIATES NSLS-II Strawman Capabilities Possible distribution among beamline categories (and compared to existing NSLS) N.B. NSLS-II distribution includes some canting (principally, damping wigglers) and also leaves 3 straights unassigned.

6 BROOKHAVEN SCIENCE ASSOCIATES Project Beamlines Project goal: To 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. The beamlines are: 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) Total = $65.2 M (direct, FY06 dollars) EFAC Approved these choices: May 10 th, 2007

14 BROOKHAVEN SCIENCE ASSOCIATES Beamline Development “Develop policy whereby the design, construction, and operation of all beamlines, Beamline Access Team (DOE funded) and Beamline Development Team (non-DOE funded) beamlines, will be the responsibility of Experimental Facilities staff.” DOE Guidance

15 BROOKHAVEN SCIENCE ASSOCIATES Beamline Access All beamlines will have at least 50% GU time Partner User Proposals can be up to 30%. (User groups partnering with the facility) Staff time up to 20% Steady State operations Note, this is also true for Externally Funded Beamlines Includes non-BES DOE, NIH, NSF, State… Funds to flow through facility Facility will design, build and operate the beamline External group can operate as PU, but most likely mode of operation is to support a full GU program.

16 BROOKHAVEN SCIENCE ASSOCIATES Beamline Advisory Teams (BATs) Facility has ultimate responsibility for design, construction and operation for all beamlines. BATs will : 1)Propose scientific mission and technical capabilites of beamline (reviewed by EFAC, chosen by facility). 2)Work closely with the facility to advise them during design, construction and early operations. 3)Take part in periodic design reviews. 4)Represent a particular User community. 5)Report to XFD Director Considering the formation of a Beamline Council, made up of BAT Chairs, to advise facility. Meets regularly (~ twice a year?).

17 BROOKHAVEN SCIENCE ASSOCIATES BATs (BES-funded beamlines) Small teams chosen based on recommendation of EFAC, to advise on mission, design and construction of a beamline. Facility hires beamline scientists, for whom BAT acts as advisory body. BAT meets every 6 months with beamline scientist (reports to XFD Division Director and.cc-ed to EFAC ). BAT members do not get preferential access to beamtime. May continue to advise facility during operations. Applies to: All BES funded beamlines (insertion devices, 3-pole wigglers and dipoles)

18 BROOKHAVEN SCIENCE ASSOCIATES BATs (non-BES funded beamlines) BAT members appointed by fundraisers (e.g. PIs on grant, principals in industry, etc). Negotiated on a case-by-case basis. Most expected to run peer- reviewed user programs in 80:20 type mode. Staff may be facility employees or employees of external group. Does not automatically expire if operational funds continue to flow. Reviewed by EFAC every 3 years. High threshold on staffing, technical quality and scientific productivity metrics. Applies to: non-BES DOE, NIH, NSF, State funded, industrial…
