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

9
Sloan Digital Sky Survey

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

2.5 m Telescope
Mosaic Imaging Camera
640 Fiber Spectrograph
Telescope in New Mexico

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

Pierre Auger high energy cosmic ray detector
array (w/NSF foreign partners)
3000 km2 site in Argentina As of Fall 2003, it
became the largest air-shower detector in the
world
water Cherenkov surface detectors
Fluorescence telescopes

• 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

12
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
Oodham 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
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

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

14
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.

15
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
  DOEs 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
• RD efforts planning
• Continuing RD 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

16
DOE HEP Future Planning

• In order to inform the Department of OHEPs
  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 ?13
• Electron-neutrino appearance experiment -
  accelerator-based, to measure ?13 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.
