Accelerator-based physics is our primary tool.
Construction & operation of accelerators and detectors
Proton based: Fermilab Tevatron – top quarks, Higgs search, extra dimensions, supersymmetry; neutrino studies - NuMI, MiniBooNe, K2K Electron based: SLAC – b quarks, CP violation; also Belle Future: Large Hadron Collider at CERN in Geneva, Switzerland and R&D for International Linear Collider • •
Non-accelerator physics –
growing and important sector
Atmospheric and solar neutrinos: SuperK, KamLAND, SNO Particle Astrophysics and Cosmology to study dark matter, dark energy, high energy cosmic rays, high energy gamma rays – Currently: GLAST, Auger, VERITAS, SDSS, CDMS-II, AMS
• •
Theory
Elementary Particle Theory Major Computing efforts: QCD simulation, data storage, distribution & analysis •
Technology R&D
R&D for accelerator & detector technologies

The DOE HEP program in FY 2007
Office of Science
• 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 • Dark Energy R&D – SNAP ($2.9M $7.5M) – Reactor Neutrino Detector
$60M)
• Start of new neutrino initiatives – Electron Neutrino Appearance Experiment (EvA) • Investment in long-term accelerator R&D increased +$5M – R&D for concepts (ground &/or space) is $5M. Concepts will be selected by open competition, peer review; DETF will guide us – funding levels reflect tentative plan which may change based upon advice from DETF and other relevant considerations

ILC R&D
Office of Science
• • •
To support a U.S. leadership role in this coordinated international effort, DOE is doubling the ILC R&D budget in FY2007 Presidents Request ($30M
$60M)
– 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) – Also includes U.S. contributions to GDE management & support
This is a major step forward for the ILC effort, although it is NOT yet
– Approval of construction, or engineering design
The goal of the R&D program at this stage is to provide solid technical, cost and schedule information to governments to enable a decision on ILC construction around the turn of the decade.

Neutrinos
Office of Science

APS Study The Neutrino Matrix recommended several new experiments in neutrino physics, including:
– Reactor experiment to measure
13 via
e disappearance
– Accelerator-based experiment with comparable sensitivity to
13 as above AND sensitivity to mass hierarchy thru matter effects Charge to Neutrino Scientific Assessment Group (NuSAG) in 2005 explicitly asked for further recommendations on which of the possible technical options to pursue in these two areas. We are proceeding in the FY2007 request with these two experiments:
Reactor Neutrino Detector.
Site TBD. NuSAG recommends either Daya Bay (China) or Braidwood (Illinois) for scientific reasons. Site selection by DOE in 2006.
Electron Neutrino Appearance (EvA) Experiment.
Very large scintillator detector to observe
e appearance in NuMI beam. R&D for other items in the list of APS recommendations is proceeding (see later slide), in coordination with DOE Nuclear Physics and/or NSF

Other Areas

•
Progress on other experimental initiatives (not exhaustive)
• Dark energy experiment(s) • SNAP R&D continues as conceptual design for JDEM with NASA • R&D for new cameras on existing telescopes and/or new
telescopes on ground or in space
– In cooperation with NSF & NASA - based in part on DETF input • A neutrinoless double-beta decay experiment to probe the Majorana
nature of neutrinos
• 200kg Xenon experiment in operations by 2007 • R&D underway for large-scale (~1000kg) experiments with
various isotopes (with DOE Nuclear Physics, and possibly NSF)
• Dark Matter experiment(s) – direct detection • R&D for next-generation experiments, joint with NSF • Dark Matter Scientific Advisory Group (SAG) in preparation

Accelerator R&D
Office of Science
• • •
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) provide needed input for developing this program
Department of Energy
Core Research
Office of Science
• •
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 (though most R&D funding for these activities comes from other sources).
– Also includes ongoing (unchanged from FY06) HEP contributions
to the cross-cutting SciDAC program and the Lattice QCD IT investment, joint with Nuclear Physics.
