  2. Office of Science • The Office of Science is the primary source of support for the Physical Sciences. • Provides 42% of federal support to the physical sciences • Provides primary support to select sub-fields (e.g. high energy physics, nuclear physics, nuclear medicine, heavy element chemistry, plasma physics and magnetic fusion, and catalysis.) • Manages long-term, high-risk, high-payoff multidisciplinary science programs to support DOE missions • Directly supports (FY ‘05) the research of around 23,500 Ph.D.s, Post Docs and Graduate Students • Constructs and operates large scientific facilities for the future of science. • Accelerators, light and neutron sources, nanotechnology research centers • Used by more than 19,000 researchers every year • Number of users expected to increase dramatically with Spallation Neutron Source (SNS) and nanocenter user facilities commencing operations • Linac Coherent Light Source begins construction • Ten billion times brighter, in the hard x-ray range, than any other light source in the world • new field of ultra-fast science

  3. Elements of Program • Accelerator based physics : our primary tools • Construction and operation of accelerators and detectors and research activities in these facilities • Proton based accelerator: Tevatron, LHC, K2K, NuMI, MiniBooNE • Electron based accelerator: B-Factories—BaBar and Belle • Non-accelerator physics • Atmospheric & solar neutrinos: Super-K, KamLAND • Particle astrophysics & cosmology: GLAST, Auger, VERITAS, SDSS, CDMS-II, AMS, CMB • Theory • Elementary particle theory • Major computing efforts: simulation, data storage, distribution, & analysis • Technology R&D • R&D for accelerator and detector technologies

  4. Cosmic Connections Operating: Sloan Digital Sky Survey – SDSS (w/NASA, NSF, Sloan foundation) 3D sky map, dark energy Supernova Cosmology Project, Nearby Supernova Factory (w/NSF & NASA) dark energy Cosmic Microwave Background (CMB) cosmology Cold Dark Matter Search (CDMS-II) (underground, w/NSF) dark matter in cosmic rays Approved & Under Construction: Large Area Telescope (LAT) – GLAST, 2007 (w/NASA, foreign) gamma rays, dark matter Pierre Auger – ground array in Argentina (w/NSF, foreign) high energy cosmic rays AMS – Alpha Magnetic Spectrometer – ISS (w/NASA, foreign) cosmic antimatter Very Energetic Radiation Imaging Telescope Array System (VERITAS) - telescope in Arizona (w/NSF, SAO) high energy gamma rays AXION dark matter search Proposed: Joint Dark Energy Mission (w/NASA) dark energy Large-aperture Synoptic Survey Telescope – LSST (w/NSF) dark energy
