6. Page 6 AAC meeting, Dec 4-6, 2006 – S. Holmes f Fermilab Accelerator R&D Program Strategic Context Fermilab has operated the highest energy particle accelerator in the world since 1983... –Current plan: Tevatron operations will cease on October 1, 2009 Fermilab currently operates the most advanced long- baseline neutrino program in the world... –CNGS now online –J-PARC will become competitive in 2010-2011

7. Page 7 AAC meeting, Dec 4-6, 2006 – S. Holmes f Strategic Context The Vision The vision is that Fermilab will remain the U.S. center for accelerator-based High Energy Physics, and one of the (two) pre-eminent centers in the world, for the foreseeable future. ILC is established as the primary goal; in parallel with strong participation in LHC and a world-leading neutrino program whose scope can be adjusted depending upon the fate of the ILC. A greater focus on longer term R&D is a key responsibility of the laboratory in the new era. Supporting this vision requires a reorientation of the mission of the accelerator organization at Fermilab to provide enhanced support of accelerator R&D aimed at the future beyond Run II.  This is the primary motivation for creation of the Accelerator Physics Center at Fermilab.

17. Page 17 AAC meeting, Dec 4-6, 2006 – S. Holmes f R&D Program Elements Current Status and Issues The role of future directed R&D in the Fermilab program? –Not a traditional strength or point of emphasis within the laboratory –Fermilab’s primary mission is operations and will remain so (we hope) for decades; generally translates into emphasis on near and intermediate terms –However, as the center of U.S. accelerator-based HEP at the end of the decade we recognize a responsibility to invest effort in the generation beyond.  “Discretionary” R&D is important for maintaining flexibility for the future.  These efforts often provide the best opportunities for the training of students and other staff.  Planning to migrate the AARD program from the A0 photoinjector to the NML_ILC Test Area, accompanied by exploration of possible off-site opportunities

24. Page 24 AAC meeting, Dec 4-6, 2006 – S. Holmes f Summary We are managing a significant buildup of accelerator R&D in support of laboratory’s long-term strategy –Accelerator Physics Center being created to facilitate increased focus on R&D –Balancing resources to support the operating program with those needed for R&D is part of the challenge –We are doing this within an extensive collaborative framework involving outside laboratories and universities –Some consolidation will probably be required if/as ILC support doubles Advanced accelerator R&D aimed at the long term will be an important and increasing activity, but it will not be dominant Your charge is to consider all this and offer advice…

25. Page 25 AAC meeting, Dec 4-6, 2006 – S. Holmes f Charge to the Committee: Overview of the entire program and commentary on strategy and balance –Impossible to cover all elements in detail so if there are particular items which the committee would like more in-depth discussion that can be arranged for tomorrow. ILC: Is the strategy for preparing Fermilab as the best possible host sound? –The approach here is to get the committee to look at the big picture and assist Fermilab in defining and implementing the best possible strategy –Go into areas where the GDE/MAC and DOE/ART reviews don’t tread

26. Page 26 AAC meeting, Dec 4-6, 2006 – S. Holmes f Charge to the Committee: APC: How can we set this up to utilize our assets most effectively in supporting the present while preparing options for the future? –Special emphasis on the Muon Collider R&D proposal and the strategy for migrating AARD to NML

27. Page 27 AAC meeting, Dec 4-6, 2006 – S. Holmes f Charge to the Committee (Rev. 2) At its December 2006 meeting the Fermilab Accelerator Advisory Committee will take a broad look at the entire Fermilab accelerator R&D program, accompanied by a more focused look in areas in which Fermilab is planning new initiatives to provide enhancements to our advanced accelerator R&D program aimed at the post-Run II era. The primary topics for review and discussion are:

28. Page 28 AAC meeting, Dec 4-6, 2006 – S. Holmes f Charge to the Committee (cont.) Overview of the Current Accelerator R&D Program We will provide a brief overview of the accelerator R&D program at Fermilab. Topics to be covered include the ILC, LARP/LHC, Neutrino, Muon, and Advanced Accelerator R&D programs. The primary intent of the overview is to provide a contextual framework for more detailed discussion on new initiatives. However, the committee is invited to provide any comments, suggestions, or recommendations they might have regarding the overall strategy, balance, and effectiveness of the program as a whole.

29. Page 29 AAC meeting, Dec 4-6, 2006 – S. Holmes f Charge to the Committee (cont.) Fermilab Strategy on the International Linear Collider In our role as the preferred U.S. site of the ILC, Fermilab has a special responsibility for providing leadership within the ILC development effort while preparing itself, and northern Illinois, for a possible host role. We will be discussing Fermilab’s strategy for ILC activities leading up to a possible decision to construct. The goal of this strategy is to have Fermilab fully prepared and recognized as an outstanding host site for the ILC if the decision to construct is made at the end of the decade. We would like comments and recommendations from the committee regarding all aspects of Fermilab’s strategic approach including: technology development & industrialization, accelerator design, site specific design, state of Illinois involvement, and community outreach; and the integration of these activities within both local and international efforts. The committee will recognize that many of these strategic elements are not currently fully developed. Nevertheless, we are asking the committee to look at all these elements from the Fermilab perspective in providing us with advice and/or guidance.

30. Page 30 AAC meeting, Dec 4-6, 2006 – S. Holmes f Charge to the Committee (cont.) Creation of the Fermilab Accelerator Physics Center In order to enhance the Fermilab accelerator R&D program aimed at the future, we are in the initial stages of creating an Accelerator Physics Center at Fermilab. The goal is to create an effective organization for support of the Fermilab mission, with particular emphasis on the post-Run II era. The APC will bring under one roof staff dedicated to providing direction and/or support to all accelerator R&D activities aimed toward the future. We will be describing our current vision of the goals, strategies, and plans for the center. Particular emphasis will be placed on the possibilities afforded for enhanced accelerator physics activities in support of ILC, on opportunities opened up by migrating the AARD program currently centered at the A0 photoinjector to the ILC Test Area being planned for the end of the decade, and on possibilities of undertaking an expansion of our muon program to explore more deeply the long-term possibility of a multi-TeV lepton collider based on muons.

31. Page 31 AAC meeting, Dec 4-6, 2006 – S. Holmes f Charge to the Committee (cont.) AAC input is important at this time since the plans for the APC are not yet set in stone. The committee is asked to review and offer comments, suggestions, and/or recommendations on all aspects of the APC as currently proposed, including: goals, strategy, organization, and implementation. Commentary on specific unique opportunities that could be realized through this initiative would be greatly appreciated. Fine Print As usual the committee is invited to issue comments or suggestions on any aspect of the programs discussed beyond those specifically included in this charge. It is requested that a concise report responsive to this charge be forwarded to the Fermilab Director by February 1, 2007. Thank you.
