The DOE HEP program
in FY 2006
Office of Science
 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
Office of Science
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.
Blue line – new results
Dotted Blue line – expected full results

water Cherenkov surface detectors
As of Fall 2003, it
became the largest
air-shower detector
in the world
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
U.S. Department of Energy
Very Energetic Radiation Imaging Telescope Array
System - VERITAS
Office of Science
 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
Office of Science
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. 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

Dark Energy –
Planning & Future
Office of Science

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
Office of Science
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.
