Department of Energy Office of Science HEP FY08 Budget Status and Issues Robin Staffin preCRB Discussion April

Department of Energy Office of Science HEP Priorities FY08 and beyond Support current world-leading U.S. user facilities: –Tevatron Collider through 2009, and NuMI/MINOS through 2010 –Sustain B-factory to run as long as scientifically competitive, but no later than 2008 Develop new facilities in targeted areas that will establish a U.S. leadership role in these areas in the coming decade: –Enable U.S. researchers to take leading roles in LHC physics –Support the Joint Dark Energy Mission with NASA and explore options for ground-based dark energy experiments with NSF –Invest in neutrino initiatives to address outstanding questions: EvA/NOvA and reactor neutrino experiments –Invigorate R&D for International Linear Collider Restore core research and long-term R&D activities

Department of Energy Office of Science HEP Highest Priority : ILC The proposed International Linear Collider (ILC) is HEP’s highest priority. The Department has expressed its interest in siting the ILC at Fermilab, should it be built and the United States be chosen as the host country. The out-year budget profile includes support for technology R&D activities aimed at technical design goals while reducing project risk and cost –R&D profile is much improved vs. FY07 but still lags behind Europe –Will support an international decision-making process near the end of this decade. A future decision to proceed with construction rests on two conditions: –the ILC is deemed a priority and affordable by its international partners; and –the anticipated new science at the ILC is supported by clear physics results at the LHC.

Department of Energy Office of Science HEP Outyear Trends by Activity

Department of Energy Office of Science Overarching Issues The HEP program in is a combination of: –LHC (including upgrades) –Neutrinos (MINOS  EvA, Reactor Nu, Double Beta Decay?…) –Dark Energy and Dark Matter –ILC R&D  construction? Is this a “leadership” program? Does it provide enough opportunities for students? For the rest of the community? If ILC does not happen, what then?

Department of Energy Office of Science FY08 Issue: ILC R&D ILC R&D and pre-construction budget has evolved from a “technically- driven” one with construction start in to a budget-driven one with construction start in –Partly due to overall SC budget constraints –Also partly due to OMB/OSTP “optics” constraints See following slides –Shortfall relative to technically-driven schedule is $38M in FY08 [FY08 ILC R&D budget is $75M vs. est. need of $113M] Most of shortfall is in ramp-up of US industrialization effort International partners/competitors (Europe, Asia) are investing at least this much in near term: –Estimated European FY08 expenditure: $130M Includes test facilities and industrialization –Japanese effort is ~comparable to U.S. plan (no detailed #s yet); plus growing efforts in Korea, China, India Impact of shortfall is that we will not be ready in time with industrially-produced components that can verify technical readiness

Department of Energy Office of Science Broader Impacts of ILC (Money makes the World go ‘round) But SRF also has broader applications…

Department of Energy Office of Science Other FY08 Issues There are other (smaller) FY08 resource issues that we are handling within the HEP Target: –Fermi RunII +$6M projected power rate increase in FY08 vs 07 –Revised EvA profile (TPC was $150M, now ~$250M) –Funding for SLAC advanced accelerator R&D facility (SABER) –Division of SLAC GPP and maintenance activities (with BES, TBD) To solve these problems we had to make priority decisions: –Slowed recovery of core research and R&D programs –Stretched-out or deferred dark energy initiatives –Drop or find other funding sources for small neutrino experiments –Dropped participation in NP-led double beta decay experiment

Department of Energy Office of Science A Future without ILC Cue the violins

Department of Energy Office of Science “Decrement” Items B-factory Operations –To generate a 1.5% SC-1 reserve, we would eliminate $10M from FY08 SLAC Ops budget, severely reducing B-factory run time [need estimate] –Additional reductions could be taken (up to ~$20M) but this implies significant RIFs, end of Bfactory program EvA/NoVA construction –Could reduce funding profile for EvA construction (up to $20M) –Consistent with “wait and see” approach on ILC –Incurs schedule delay, risks some loss of competitiveness with respect to Japanese experiment Core Research and R&D –Hold at FY07 dollars (-$15M) –Inadequate to fully cover research needs of both Tevatron and LHC while closing out B-factory analysis –No funding for small but important efforts in: dark energy, neutrinos, advanced accelerator R&D (SABER)

Department of Energy Office of Science FY08/Outyear Issues Construction  EvA/NoVA profile is back-loaded; not much $$ available until B- factory Ops starts to roll off in FY09  Also total cost issues; may need a lot more resources (nominal TPC $150M; current estimate ~$200M+)  Plus incremental NuMI upgrades…  Front-loading profile as much as possible will reduce cost and schedule risk  Need to consider de-scope options  No other construction projects in pipeline until ILC $ in MFY07FY08FY09FY10FY11 Nominal Profile TPC=150M Current Estimate TPC=210M 1050
