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

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 km2 site in Argentina

As of Fall 2003, it became the largest air-shower detector in the world

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 Spectrometerw/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 3rd 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.
