  1. Transition from NSLS to NSLS-II Chi-Chang Kao Chairman, NSLS NSLS-II EFAC October 5, 2007

  2. National Synchrotron Light Source • One of the most productive synchrotron facilities in the world for the last two and half decades • Today NSLS supports the research of more than 2000 users annually. The research from users and staff results in more than 900 publications, of which more than 25% are published in high impact journals • NSLS users have received numerous honors and awards for the work performed here • It’s a tribute to our users and staff and the unique research environment we created together

  3. Transition from NSLS to NSLS-II • The extraordinary properties of NSLS-II will provide challenges and opportunities for decades to come • A transition that is unprecedented in it’s scale and requires detailed planning and close coordination between the NSLS and NSLS-II project • The scope includes four major interconnected parts • Transition of scientific programs • Transition of beamlines and endstations • Transition of user access model • Transition of staff

  4. Goals • Ensure a “Smooth” transition • Realize the opportunities offered by the transition • Minimize the potential negative impact

  5. I. Scientific Program Transition 1. Orienting the scientific program towards NSLS-II • NSLS five-year strategic plan has identified several broad areas of science that will benefit most from NSLS-II : Nanoscience, Energy and Imaging http://www.nsls.bnl.gov/newsroom/publications/manuals/5YearPlan.pdf • Work with existing user community and outreach to new user community, and NSLS scientific advisory committee to develop specific scientific programs within those areas

  6. I. Scientific Program Transition (cont.) • Develop long range white papers for major program areas to translate the scientific challenges to an overall plan for beamline/endstation upgrades at NSLS, and new beamline/endstation proposals at NSLS-II -Crosscutting science reviews by NSLS SAC in 2008 -DOE review in 2008 -Major revision of the NSLS strategic plan

  7. I. Scientific Program Transition (cont.) 2. Transition of Research Resources/consortiums and PRTs Work with research resources, such as PXRR, Case Center for Synchrotron Biosciences, COMPRES, Catalysis consortium, on their renewal: evolution of their scientific programs, role in operating beamlines Work with PRTs on their long term plan and transition plan -NSLS beamline review in 2008 -DOE review in 2008

  8. Ex: COMPRES • Consortium for Materials Properties Research in Earth Sciences (COMPRES), an organization that facilitates the operation of high-pressure beamlines for earth science research, including four beamlines at the NSLS – has been renewed through the National Science Foundation • The five-year, $11.5 million cooperative agreement takes effect on May 1, 2007. That total includes more than $4 million for the operation of NSLS beamlines X17B2, X17B3, X17C, and U2A • An area that will benefit from the properties of NSLS-II. New funding opportunities, including BES and NNSA in addition to NSF

  9. Ex: COMPRES (cont.) The way we have been working together -Leverage investment: NSLS on beamline, COMPRES on endstations; joint hire between Stony Brook mineral physics institute and NSLS -COMPRES played an important role in developing a white paper for high pressure research at NSLS-II and organizing a NSLS-II user workshop breakout session -Expanding high pressure research into new areas Looking towards the future -Evolution of COMPRES’ role -Beamlines/endstations transition

  10. II. Beamline/Endstation Transfer 1. Rationale • Ensure significant capacity for NSLS-II at the commencement of operation to accommodate the large number of users from NSLS • NSLS-II large gap dipole (for far-IR), soft bend, three-pole wiggler are world-class sources for many experimental techniques • Many NSLS beamlines, with proper upgrades funded by DOE and other agencies, will be state-of-the-art for these sources • Recommended by Lehman review and NSLS-II Experimental Facility Advisory Committee (EFAC) • Supported by DOE/BES

  11. II. Beamline/Endstation Transfer (cont.) 2. Examples • IR beamlines: World-class at NSLS and NSLS-II • High demand / high throughput materials characterization or screening beamlines, such as x-ray absorption spectroscopy, x-ray powder/single crystal diffraction • State-of-art beamlines that do not require the brightness of insertion devices, such as full-field x-ray microscopy • State-of-art endstations or beamline components that are suitable for insertion devices at NSLS-II

  13. II. Beamline/Endstation Transfer (cont.) 3. Mechanism (proposed) • A letter of intent will be required for any PRT or facility beamline • EFAC review and approve • Submit full proposal • EFAC review and approve

  14. II. Beamline/Endstation Transfer (cont.) 4. Beamline transfer working group A beamline transfer planning group will be established at the NSLS Scope of the working group: -Identify the types of beamlines which are most suitable to be transferred -Perform detailed analysis of the performance of these beamlines and necessary upgrade for these beamlines for NSLS-II -Evaluating the quality of existing NSLS beamline/endstation, down to major component level -Coordinating major NSLS upgrade -Provide similar analysis for PRTs who are interested in transferring their beamlines to NSLS-II -Perform detailed analysis of cost and schedule for all beamline transfer after EFAC approval

Mitigating measure: re-design of the 1st crystal and its support. FEA calcs: V. Ravindranath

  18. III. Transition of User Access Mode • Almost all beamlines at the NSLS were operated by PRTs until recently. PRTs have contributed significantly to the success of the NSLS • Working closely with BES, the number of facility beamline has increased over the last few years. Today, 17 out of 65 beamlines are facility beamlines • Working under the new NSLS user access policy, a contributing user program has been established to provide another mechanism to attract the investment, both intellectual and financial, from the scientific community at large. Today, 12 CU groups are working with the NSLS.

  19. III. Transition of User Access Mode (cont.) • With increasing NSLS operating funding expected from American Competitive Initiative, we will better staff the existing facility beamlines and expand the number of facility beamlines • We will work with PRTs to transition them into contributing users or general users • Discussion with individual PRT on all aspects of this transition has begun

  20. IV. Staff Transition • The dedication and talent of the NSLS staff are essential to the success of the NSLS and will be to the success of NSLS-II • We have re-organized the department recently to better position the staff for the future. The organization will continue to evolve to meet the changing needs • NSLS and NSLS-II are coordinated closely on staff transfers between NSLS to NSLS-II to ensure we meet the goals of both in the short term • Working with NSLS-II to develop a long term staff planning to address staff concern • NSLS will also work with PRTs on their staff issues

  21. Summary • Transition from NSLS to NSLS-II is an important and complex task that requires detailed planning and close coordination between NSLS and NSLS-II project • We have identified the scope and begun to develop a comprehensive plan • Steady increase of NSLS staff is essential to ensure the success of this transition
