## The DOE HEP program in FY 2006

- Overall HEP budget and priorities in FY 2006:
- Tevatron and B-factory will be fully supported – these are our two major operating facilities
- LHC preparations will be fully supported
- A reasonable level of support has to be maintained for the core research program in the universities and laboratories
- Investment for mid- and long term new initiatives will come from redirection
- DOE will not proceed with the BTeV project at Fermilab

## Sloan Digital Sky Survey

- 2.5 m Telescope

- Mosaic Imaging Camera

- 640 Fiber Spectrograph

- Telescope in New Mexico

**Taking data since 1998 - continues**
**Oct 2004 - 3****rd**** public data release**
** ****Data for 141 million objects over 5282 square degrees**
** ****Jan. ’05 – baryon oscillation measurement**

## Cryogenic Dark Matter Search

**Purpose:  direct detection of Weakly Interacting Massive Particles (WIMPS)**
**Location - Soudan Mine in Minnesota**
**Data-taking: partial operations started in 2003, full operations with 5 towers started recently & will continue until mid-2006**

**Results – April 2005**
**...****set the world's lowest exclusion limits on the WIMP cross section by a factor of 10 compared to other experiments, ruling out a significant range of neutralino supersymmetric models. **

**CDMS-II ******

**Blue line – new results**
**Dotted Blue line – expected full results**

##  Pierre Auger – high energy cosmic ray detector array (w/NSF & foreign partners)

**Partial operations have started – construction expected to be completed by early 2006.**
_**Current status:**_
** ****18 (out of 24) fluorescence telescopes operating**
** ****833 (out of 1600) surface Cherenkov detectors deployed, 758 operating**

**3000 km****2**** site in Argentina**
**As of Fall 2003, it became the largest air-shower detector in the world**

**Fluorescence telescopes**

**water Cherenkov surface detectors**

## Very Energetic Radiation Imaging Telescope Array System - VERITAS

- Study of sources of very high energy gamma-rays in range of 50 GeV-50 TeV -- study extreme acceleration mechanisms
- Location: Kitt Peak
- 4 telescope array started construction Oct. 2003
- Operations start Oct. 2006
- Prototype telescope built and tested successfully
- Partnership of DOE & NSF with contributions from Smithsonian + foreign

**All work at Kitt Peak was stopped at the end of April pending resolution of a legal action due to environmental/historical issues by the Tohono O’odham Indian Nation.  NEPA & NHPA being redone.  Fabrication is proceeding at Whipple & universities on schedule.  Hopefully work can start again in early Fall.**

## Gamma Ray Large Area Space Telescope (GLAST) Mission

- Primary Instrument:  _Large Area Telescope (LAT)_
- -     Collaboration between NASA, DOE, France, Italy, Japan, Sweden – managed at SLAC.
- Recently had to be rebaselined.  DOE’s contribution was increased by $3M to $45M, where it has been capped.
- DOE’s remaining scope is now well-defined deliverable – electronics modules.
- LAT scheduled to leave SLAC in early 2006 – to NRL for environmental testing

**Measurement of high energy gamma rays from space**
**  ****- Energy and direction of gamma rays from 20 MeV to 300 GeV over wide field of view**
**  ****- launch in 2007**

## 		AMS - Alpha Magnetic Spectrometerw/NASA + foreign partners 

**search for dark matter, missing matter & antimatter  on the International Space Station**
** **
**Prototype (AMS-01) took data on STS-91 in 1998**
**AMS-02 fabrication complete in 2005**
**Launch and deployment on ISS currently planned for 2008.**

## Dark Energy – Planning & Future

- Developed DOE/NASA Joint Dark Energy Mission (JDEM) plan for a joint space-based mission – plan released 11/03
- Science Definition Team formed;  meetings 11/04 and 2/05
- Purpose: lay out the level 1 science requirements of a space-based dark energy mission
**JDEM is a high priority (tie for 3****rd**** place) in DOE’s Facilities for the Future of Science 20 Year Plan**
**JDEM & Large Survey Telescope (LST) are highest priority in the Interagency Physics of the Universe report**
**Current Work:**
**Supernova Cosmology Project (SCP) –** continuing ground and HST measurements to collect statistics over large redshift range
**Nearby Supernova Factory (SNFactory)** – large sample of nearby supernovae to study properties in detail
**R&D efforts & planning**
- Continuing R&D activities for SNAP — a concept for JDEM, using supernovae
- Dark Energy Survey (DES) – new camera for Blanco 4m telescope at CTIO - using galaxy cluster counting & spatial clustering of galaxies – scientists are investigating participation
- Large Synoptic Survey Telescope (LSST) – using weak lensing - scientists are investigating participation

## DOE HEP Future Planning

- In order to inform the Department of OHEP’s intent to pursue several new scientific
- topics, we are preparing draft portfolio of medium-sized mid-term experiments
- Have compelling scientific case for:
- Neutrino experiments such as:
- reactor-based neutrino experiment to measure θ13
- Electron-neutrino appearance experiment - accelerator-based, to measure θ13 & resolve mass hierarchy
- neutrino-less double beta decay experiment to probe the Majorana nature of neutrinos
- Astrophysics:
- Underground experiment to search for direct evidence of dark matter
- Ground-based dark energy experiment
- HEPAP subpanels will recommend which proposals to pursue.

## FY 2005 Funding Allocation

- Accelerator based physics (proton & electron)  ~74%
- Non-Accelerator physics ~6%
- Theory ~6%
- Technology R&D ~13%
