3 BROOKHAVEN SCIENCE ASSOCIATES “Lehman” CD-1 Review, December ) R+D program is appropriate 2) Funding for beamlines not sufficient to demonstrate unique capabilities of NSLS-II or meet user demand. 3) Include beam diagnostic BM beamline as part of the project 4) Include mirror metrology R+D in the project 5) Develop beamline access policy in which facility has the responsibility for design, construction and operation of all beamlines. 6) Establish collaborations for design, testing of BL components. Overall, the review was very positive in regard to the NSLS-II design and team. Recommendations for XFD :

7 BROOKHAVEN SCIENCE ASSOCIATES Three-pole Wigglers Added to give the users access to hard x-ray dipoles without big impact on the emittance. ~15 added to the lattice

8 BROOKHAVEN SCIENCE ASSOCIATES Radiation Sources: Brightness

9 BROOKHAVEN SCIENCE ASSOCIATES Radiation Sources: Flux

10 BROOKHAVEN SCIENCE ASSOCIATES Radiation Sources: Infra-Red New “extra-large” gap dipoles (90mm) boost performance in far-IR.

11 BROOKHAVEN SCIENCE ASSOCIATES Recent Activities Explored use and impact of the addition of a few extended straight sections (up to 18m). Decision to pursue 15-fold lattice for CD-2, but in parallel explore “upgrade path” to lattice to allow for 3 extended straight sections. Can be implemented without changing circumference. Work on user requirements for stability – part of Stability Task Force and workshop (April 18-20). For 1nm and 0.1meV: 10% stability goal for electron beam seems compatible with experiments, if supplemented by state-of- the-art beamline feedback (will require some detector R+D). Some techniques, e.g. IR, imaging and PX, need beam position stability <10% of beam size. BL Feedback probably req’d.

12 BROOKHAVEN SCIENCE ASSOCIATES Recent Activities, continued Identified 6 Project Beamlines Present to EFAC now and Users in 2 weeks, Reworking schedule in light of this decision User meeting set: July 17 th, 18 th 2007 Present design and solicit feedback and input Discuss project BLs Discuss transition from NSLS to NSLS-II Lab space requirements identified for R+D activities.

13 BROOKHAVEN SCIENCE ASSOCIATES Hiring Update Requisitions have been cut and job descriptions posted for 11 positions: 1)Inelastic Beamline group leader 2)Nanoprobe beamline group leader 3)1nm R+D Group leader 4)0.1 meV R+D Group leader 5)Interface manager 6)Deposition scientist 7)Deposition post-doc 8)X-ray optics theorist 9)X-ray optics theory post-doc 10) Assist. Phys. 0.1 meV 11) Post-doc 0.1 meV Active recruitment underway for all these, interviews are ongoing and in many cases offers are imminent.

14 BROOKHAVEN SCIENCE ASSOCIATES Responses to EFAC suggestions 1) Recommend proactive plan to move beamlines from NSLS to NSLS-II to satisfy large existing user community. -Plan is being developed (Hulbert’s talk) 2) Investigate routes to increase brightness. Specifically 3 vs 3.6 GeV and multiple in-line undulators -Minimal increase in B below 15 keV for 3.6 GeV -Extended straights under active investigation as modification to CD2 lattice. (Ozaki’s talk)

15 BROOKHAVEN SCIENCE ASSOCIATES Responses to EFAC suggestions 3) Keep project attention on realistic heat load issues, focus on project beamline requirements and justify motivation for canted damping wigglers -For undulator calculations, these suggestions have been taken on board. -Damping wigglers have been added to project beamlines, driving the need to address these issues now -Canted devices provide brighter sources for e.g. PX (Berman’s talk) 4) Beamlines should be dedicated to a single technique unless appropriate sharing possible -Agreed.

16 BROOKHAVEN SCIENCE ASSOCIATES Responses to EFAC suggestions 5) Support large gap dipole chambers for far IR. Consider slotted mirrors for heat load issues. Consider effects of top-off on IR -Done (Carr’s talk) 6) Question if the asymmetric optics scheme can be used at 1 meV as well as 0.1 meV and to consider multiplexing analysers. -The same scheme can also run at 1 meV, with significant advantages over traditional schemes (see CDR) -Multiplexing analysers has not yet been looked into.

17 BROOKHAVEN SCIENCE ASSOCIATES Responses to EFAC suggestions 6) Kinoform calculations In process of hiring theorist for this. Calculations in optical limit support diffraction limited performance. (Evans- Lutterodt’s talk) 7) Optics R+D metrology needs to be beefed up. -The project agrees with this and is working to place funds in FY08 and beyond for this effort. Lab space needs have been identified for clean-room, etc.

18 BROOKHAVEN SCIENCE ASSOCIATES Responses to EFAC suggestions 8 ) BAT allocations should be 21.25% over first four years -Such allocation schemes are still on the table. There have been a number of discussions on related issues with the DOE. This remains an on-going issue. (Hill’s talk).

19 BROOKHAVEN SCIENCE ASSOCIATES Charge to EFAC Do the project beamlines selected provide a minimal set of capabilities that both take advantage of the properties of the NSLS-II beam and provide work-horse capacity for a significant number of users? Is the process to define the scientific mission for these beamlines a reasonable one? Does it ensure appropriate user involvement? Is the schedule reasonable? Is the scope of the plan to move beamlines from NSLS to NSLSII at the start of the operations sufficient? (Range of techniques available, user capacity) Is the process to develop this plan further a reasonable one? Does it have appropriate involvement of all the necessary stakeholders? Some questions we would particularly like feedback on include:
