2. 2 BROOKHAVEN SCIENCE ASSOCIATES Reasons for Transferring Beamlines to NSLS-II User demand Ensure significant capacity for NSLS-II at the commencement of operation Lehman review recommendation EFAC recommendation N.B.: DOE BES supports this initiative

3. 3 BROOKHAVEN SCIENCE ASSOCIATES Scope and Criteria Scope: On the order of 20 beamlines Primarily techniques with high demand and high productivity Mainly occupy 3-pole wigglers, soft-bends, and large gap dipole (far-IR) Certain endstations may go to insertion device beamlines Criteria for “ movability ” : Scientific productivity, measured by # of publications Operational strength, measured by usage and user demand Technical quality & compatibility of beamline hardware with NSLS-II sources Technical quality of endstation hardware Consistent with NSLS-II scientific program planning

4. 4 BROOKHAVEN SCIENCE ASSOCIATES NSLS Beamline Transition Plan 1) Each of the existing beamlines at the NSLS, grouped by technique, was evaluated in terms of technical suitability for moving to a soft bend, a 3-pole wiggler, or an insertion device at NSLS-II. 2) Moving costs and costs associated with upgrading equipment to be suitable for NSLS-II were estimated (under the assumption that beamlines planned to be moved would be maintained at close to state-of-the-art in the interim). 3) The productivity (number of publications and premier publications) and user demand (hours requested) of the existing NSLS beamlines were evaluated. 4) From this list, and the technical and cost considerations, a suite of bending magnet beamlines were identified that would support the largest number of users with the greatest scientific impact.

Movability exercise results : Nearly all operating NSLS beamlines (Facility and PRT) were considered to have at least a portion of their hardware worthy of moving to NSLS-II. Therefore, a greater degree of selectivity was required…

12. 12 BROOKHAVEN SCIENCE ASSOCIATES Schedule optimization For each beamline group (by technique), develop a moving schedule which seeks to minimize any dip in the total (NSLS + NSLS-II) usage of the beamlines in that group during the transition period. Within technique groupings of the 20 to-be-moved beamlines, move those beamlines which need the least technical upgrade last. This will minimize the time span of the transition period. Ensure that NSLS users (both general and PRT users) are not unfairly impacted by interruptions in beamline operations associated with moving beamlines to NSLS-II. For example, NSLS should coordinate the integration of “ displaced ” users among the remaining beamlines of a given technique.

13. 13 BROOKHAVEN SCIENCE ASSOCIATES Further input and timeline Further input to be sought Proposals from PRTs User community, through NSLS UEC NSLS SAC NSLS-II EFAC Timeline Develop a strawman for discussion and planning purposes Seek input and feedback on the plan from advisory committees, and user community Refine understanding of technical suitability of beamlines and/or components Develop a detailed plan to be endorsed by NSLS SAC and NSLS-II EFAC To be completed by summer 2008
