Department of Energy Office of Science Yet Another Report from DOE Office of High Energy Physics Presented to SLUO September 10, 2006 Dr. Robin Staffin Associate Director of Science for High Energy Physics DOE

Department of Energy Office of Science 3 As in human history, one cannot know the future with certainty, but it is important to know the Times, and its opportunities: –War or Peace; –Economic Boom or Depression; –Cultural Renaissance or Dark Ages… Particle Physics is entering the age of the Terascale –The reigning theory (standard model) is as precise as it is incomplete. –How the weak and electromagnetic forces unify is a mystery –…but the consequences are likely dramatic. We are poised for great discovery. Dark Energy & Dark Matter: what are they, and how (do?) they relate to the Terascale? Neutrinos – what are they telling us? Context

Department of Energy Office of Science 4 Today’s Major Tools: Currently Running U.S. HEP Accelerator Experiments B-factory at SLAC MINOS Tevatron at Fermilab

Department of Energy Office of Science 5 Tomorrow’s Major Tool

Department of Energy Office of Science 6 The DOE HEP program request for FY 2007 Overall HEP budget and priorities in FY 2007: –Tevatron and B-factory supported for full scheduled Ops –LHC Support (Ops and Computing) up 8% as construction completes –Core research program at the universities (6%) and laboratories (2%) increased –Initiatives for the future of HEP: ILC R&D doubled ($30M  $60M) Dark Energy R&D significantly increased. Start of new neutrino experiments –Electron Neutrino Appearance Experiment (EvA) –Reactor Neutrino Detector Investment in long-term accelerator R&D increased +$5M Congressional Reaction to Administration request –House –Senate Appropriations Committee

Department of Energy Office of Science 7 Supporting the transition: HEP budget up 8% in the FY2007 Request. International Linear Collider R&D Request Doubled: ($30M to $60M) Full operations at Fermilab Tevatron and SLAC B Factory Preparing for LHC operations –Detector commissioning/computers/software up 5% in FY2007 –US participation up: CMS at ~ 30% US. ATLAS ~ 25%. Dark Energy funding up significantly by ~ $10M from $3M. Advanced Accelerator R&D $28M -> $33M Core research program at the universities up ~5%. Preliminary engineering design for an Electron Neutrino Appearance experiment at Fermilab Congressional Reaction to Administration request –House –Senate Appropriations Committee

Department of Energy Office of Science 8 High Energy Physics FY 2007 Budget Request ($M)

Department of Energy Office of Science 9 ILC R&D To support a U.S. leadership role in this coordinated international effort, DOE is requesting a doubling the ILC R&D budget in FY2007 Presidents Request ($30M  $60M) –Would enables significant progress on all major subsystems –Begins industrialization of key components so that U.S. industry can get “up to speed” and successfully compete for contracts if ILC is built –Includes detector R&D funding (a change from previous years) This is a major step forward for the ILC effort, although it is NOT yet –Approval of construction, or engineering design Our goal for the R&D program at this stage is to provide solid technical, cost and schedule information to governments for a decision on ILC construction around the end of the decade.

Department of Energy Office of Science 10 Core Research We are supporting core experimental and theoretical research at labs and universities to maintain approximately the FY 2006 level-of- effort, or slightly above: University-based physics research up ~6% overall Lab-based physics research up ~2% overall Goals: –To maintain strong participation in the Tevatron, B-factory and LHC physics programs –To help support research activities associated with new initiatives such as ILC R&D, neutrinos, dark energy, and dark matter. –Also includes ongoing (unchanged from FY06) HEP contributions to the cross-cutting SciDAC program and the Lattice QCD IT investment, joint with Nuclear Physics.

Department of Energy Office of Science 11 Accelerator R&D In addition to increases in ILC R&D, there is in the FY2007 request an additional significant increase (+$5M, or ~18%) in the long-range R&D program that supports fundamental research into the physics of beams and accelerator technologies (“accelerator science”) The goal is to enable the restoration of the accelerator science research program to the level needed to support long-term R&D on new particle acceleration techniques and technologies, such as: –Novel particle acceleration concepts –New superconductors and their application –Very high gradient accelerating structures –Advanced beam instrumentation –Theory and simulation of beams –User facilities to test these concepts Advice from the community (e.g., J. Marx AARD panel) provides needed input for developing this program

Department of Energy Office of Science 12 Advisory Committees -- Our Scientific Anchor EPP2010 National Academy Study –Provides and broadly underpins a strategic future for US High Energy Physics. This study broke real ground. High Energy Physics Panel (HEPAP): reporting to DOE and NSF –Expanded to 25 members, with members from Europe and Asia We’ve put HEPAP to work –P5 doing a budget-based roadmap, in the strategic context of EPP2010. Awaiting the first roadmap report, due shortly. –Scientific Assessment Groups (SAGs): Neutrino SAG (NuSAGi) Dark Matter SAG underway. –Dark Energy Task Force reported out. –Advanced Accelerator R&D Subpanel reported out. –University Subpanel HEPAP ILC/LHC Synergy Study: Exploring the Quantum Universe, as well as key input to EPP2010 Our panels, as a matter of policy, now include as full members, leading scientists from Europe and Asia

Department of Energy Office of Science 13 US High Energy Physics at a Crossroads Is there, will there be, a community-wide vision? –EPP2010 and P5 roadmap as the basis for a broad vision. The stronger the consensus, the better chance we have at achieving our goals. If it business as usual, every experiment for itself, these chances will diminish significantly and rapidly. Most of these proposed experiments require significant, large resources; but the science can be exciting for a broad audience, and will likely be of great historical significance. What do you want the long-term future of US particle physics to be, and what are you willing to do to promote a common vision?

Department of Energy Office of Science 14 Secretary of Energy Bodman at Fermilab, April “Your work over the decades has led to great science, to breakthrough concepts, and to the United States’ unquestioned leadership in physics. And it has benefited our nation in many ways. The President recognizes the contribution that fundamental research makes to our nation, particularly to our economic competitiveness and to our quality of life as Americans.” “I fully support the possibility of bringing the International Linear Collider to this Lab. There are a great many difficult steps that will be needed for this to occur. This audience understands better than I just what those steps are and how difficult they will be. But it is a goal worth fighting for. This may turn out to be the most profound new science that we will be seeing in our lifetime.”
