## High Energy Physics Briefing to theAstronomy and Astrophysics Advisory Committee

**Associate Director, Office of High Energy Physics**
**DOE Office of Science**

## DOE Office of High Energy Physics (HEP)

**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

**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) **
**Start of new neutrino initiatives **
- Electron Neutrino Appearance Experiment (EvA)
- Reactor Neutrino Detector
**Investment in long-term accelerator R&D increased +$5M**
**Dark Energy R&D **
- SNAP ($2.9M  $7.5M)
- 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

**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

**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

**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 **

## 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 (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. **
