Office of Science



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

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.

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

– remaining scope will be Has changed NASA/DOE relationship

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 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) –

statistics over large redshift range  properties in detail continuing ground and HST measurements to collect

Nearby Supernova Factory (SNFactory)

– large sample of nearby supernovae to study

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

Office of Science

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 θ 13  off-axis accelerator-based neutrino experiment to measure θ hierarchy 13 & resolve mass  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.
