The DOE HEP program in FY 2006

Overall HEP budget and priorities in FY 2006:

Tevatron and B-factory will be fully supported 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 near and long term new initiatives (including

International Linear Collider R&D) should grow Any new initiatives will have to come from re-direction DOE has decided not to proceed with BTeV

Cryogenic Dark Matter Search

Purpose: direct detection of Weakly Interacting Massive Particles (WIMPS)

Location - Soudan Mine in Minnesota

Data-taking: Started in 2003 with full operations starting in April 2005.

First results released May’04:

…set the world's lowest exclusion limits on the WIMP cross section, ruling out a significant range of neutralino supersymmetric models.

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.- Has had technical problems since baseline set in July 2003 & needs additional funds.- DOE’s contribution will increase by $3M and has been capped at $45M.- In the process of rebaselining the DOE scope/cost now – remaining scope will be

providing a well defined deliverable (data acquisition electronics and systems engineering) within the cap.

- Has changed NASA/DOE relationship

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

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) requesting R&D support – new camera for Blanco 4m telescope at CTIO - using

galaxy cluster counting & spatial clustering of galaxies Large Synoptic Survey Telescope (LSST) requesting R&D support – using weak lensing

DOE HEP Future Planning

In order to inform the Department of OHEP’s intent to pursue several new scientific topics, we plan to prepare draft requests for approval CD-0 “Statement of Mission Need”.→ These are all for “medium-sized” proposals.

Neutrino experiments such as: reactor-based neutrino experiment to measure θ13

off-axis accelerator-based neutrino experiment 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

This process will be in parallel with a Scientific Advisory Group process that will recommend which proposals to pursue in these areas.
