  1. John HillPACMay 24th 2007 Initial Beamline Suite and Beamline Development

  2. NSLS-II Beamlines 15 five m straights for user undulators Could potentially drive up to 30 beamlines by canting two undulators 4 eight m straights for user undulators Could potentially drive up to 8 beamlines by canting two undulators 8 eight m straights for user damping wigglers Could potentially drive up to 16 beamlines by canting two DWs 27 BM ports for UV, soft X-rays and hard-xray (3PWs) 3 BM ports for far-IR At least 57 beamlines More w/ multiple IDs per straight Multiple hutches per beamline are also possible

  3. Possible Insertion Device Usage at NSLS-II • Physical Science Beamlines • 6 project beamlines in red • 16 MIE beamlines in blue • Estimate that these 22 beamlines could accommodate ~ 1300 users • Life Science Beamlines • 5 other funded beamlines • Three straights left unassigned

  4. 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. 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. 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 10th, 2007

Sci)

  8. Inelastic X-ray Scattering • Mission • Low energy modes in soft matter • Phonons in small samples (Hi-P, single crystal..) • Capabilities • 0.1 meV, fixed energy • 1.0 meV, fixed energy • Cost • $10.5 M (FY06, Direct) • Source • U19 in short straight* • *A candidate for extended straight. 0.1 meV 1.0 meV

  9. Nanoprobe • Mission • Nanoscience: hard-matter • Imaging, diffraction • Capabilities • 1nm, short working distance • 10nm, larger working distance • Possible remote hutch • Cost • $13.8 M (FY06, Direct) • Source • U19 in short straight* • *A candidate for extended straight. 1 nm 10 nm

  10. Soft X-ray Coherent Scattering • Mission • Imaging of bio samples • Hard matter, magnetic systems • Capabilities • Coherent imaging + microspectroscopy • Coherent scattering • Fast switching of polarization • Cost • $10.5 M (FY06, Direct) • Source • 2 x EPU 45 in short straight (canted at 0.25 mrad)

  11. Hard X-ray Coherent Scattering • Mission • Slow dynamics in soft matter • Nanoscale imaging of hard matter • time-resolved SAXS (biological processes) • Capabilities • XPCS/SAXS • Coherent Diffraction • Cost • $16.4 M (FY06, Direct) • Source • U19 in long straight* • *gap > 7mm Coherent Diffraction/SAXS XPCS Secondary optics

  12. Powder Diffraction • Mission • Materials Science • time-resolved catalysis • Capabilities • 5-50 keV • Analyser-mode and strip-detector mode • Sample environments (high-P, low-T, high-T..) • Cost • $7 M (FY06, Direct) • Source • 3m damping wiggler in long straight BM hutch Powder-I Powder-II

  13. EXAFS Mission Environmental science, catalysis Materials science Capabilities microprobe Cost $7 M (FY06, Direct) Source 3m damping wiggler in long straight BM hutch EXAFS-I EXAFS-II

  14. 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. 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. Beamline Advisory Teams (BATs) • Facility has ultimate responsibility for design, construction and operation for all beamlines. • BATs will : • Propose scientific mission and technical capabilitesof beamline (reviewed by EFAC, chosen by facility). • Work closely with the facility to advise them during design, construction and early operations. • Take part in periodic design reviews. • Represent a particular User community. • 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. BATs (BES-funded beamlines) • Applies to: • All BES funded beamlines (insertion devices, 3-pole wigglers and dipoles) • 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.

  18. BATs (non-BES funded beamlines) • Applies to: • non-BES DOE, NIH, NSF, State funded, industrial… • 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.
