  2. What is the Office of Science? • The Office of Science is the primary source of support for the Physical Sciences. • Provides over 40% of federal support to the physical sciences (e.g. 90% of High Energy & Nuclear Physics, 60% of Catalysis, 25% of Nanoscience) • Provides sole support to select sub-fields (e.g. nuclear medicine, heavy element chemistry, magnetic fusion) • Manages long term, high risk, multidisciplinary science programs to support DOE missions. • Directly supports the research of 15,000 PhDs, PostDocs and Graduate Students. • Constructs and operates large scientific facilities for the U.S. scientific community. • Accelerators, light & neutron sources, nanotechnology research centers. • Used by more than 19,000 researchers every year. • Infrastructure support for ten Science laboratories. 2

  3. Office of Science Vision Scientific Discovery Through 21st Century Computation National Security, a Clean Environment & Energy Security Through Basic Research Tomorrow’s Science and Technology Capabilities Revolutionary New Materials Through Nanoscience Uncovering the Origins of Time and Matter • Begin construction of ITER to demonstrate the feasibility of fusion energy. • Improved hydrogen production, storage, and use • New materials for lighter weight vehicles, more efficient engines, more efficient photovoltaic cells. • Harnessing microbes, microbial communities, and other organisms to produce energy, sequester carbon, and remediate hazardous waste sites. • Spallation Neutron Source: improved materials. • Hands-on experience in science and math research for K-14 teachers; enhancement of the diversity of the scientific workforce. • Protein Production and Tags Facility: mass produce proteins from microbial genomes, identify and tag them to harness microbes for DOE missions, e.g.: hydrogen production, carbon sequestration, bioremediation. • Linac Coherent Light Source: Stop action imaging of chemical reactions; structure determination of single molecules. • Develop computer architectures and leadership class machines that will dramatically improve hardware performance on DOE scientific problems. • Develop scientific simulation codes to fully exploit the capabilities of terascale computers for DOE problems. • For Simulation of: - Climate • Nano-Materials • Protein Folding • Cell Functions via Genomics: GTL • Origins of Mass (QCD) • Quark-Gluon Plasma • Burning Fusion Plasma • Combustion • Five Nanoscale Research Centers linked to large scientific research instruments at the DOE National Labs to enable: • High Efficiency energy storage & conversion. • Miniature sensors. • Nanocatalysts with enhanced specificity and reactivity. • Novel materials that are light weight, strong and conductive. • Low cost, high-efficiency photovoltaic cells. • Low activation materials for high-temperature applications • Understand the origins of the Universe: - Mass • Accelerating Universe/Dark energy • Dark Matter • Dominance of Matter over Anti-matter • Gravity • Create the quark-gluon plasma that existed immediately after the “Big Bang”, providing fundamental insights into the evolution of the early universe. • Understand the nature of Quarks and Gluons: internal structure of protons and neutrons. 3
