Dear Colleagues, Details of the President's FY2010 budget proposal have been released and are available at: http://www.whitehouse.gov/omb/budget/ The Department of Energy appendix is at: http://www.whitehouse.gov/omb/budget/fy2010/assets/doe.pdf High Energy Physics starts at: http://www.whitehouse.gov/omb/budget/fy2010/assets/doe.pdf#page=9 " High Energy Physics.-The high energy physics (HEP) program aims to understand how our universe works at its most fundamental level, by discovering the most elementary constituents of matter and energy, probing the interactions between them, and exploring the basic nature of space and time itself. The program encompasses both experimental and theoretical particle physics research and related advanced accelerator and detector technology research and development (R&D). The primary mode of experimental research involves the study of collisions of energetic particles using large particle accelerators or colliding beam facilities. In addition to contributing to breakthrough scientific discoveries, HEP research also makes major contributions to accelerator technology and provides the expertise necessary for the expansion of such technology into medicine, industry, and homeland security, as well as materials, biology, and chemistry research using light sources. One notable recent example is the Linac Coherent Light Source, currently under construction at the SLAC National Accelerator Laboratory: the concept and proof-of-principle for this state-of-the-art basic energy sciences facility grew out of particle accelerator technology developed for the HEP program. The HEP budget request supports a world leadership program at Fermilab (the Tevatron Collider and Neutrinos at the Main Injector [NuMI]) and phase-out activities at the SLAC B-factory, which has completed its scientific mission. Funding is provided for the Large Hadron Collider (LHC) research program, including support for software and computing, pre-operations and maintenance of the U.S. built systems that are part of the LHC detectors; and accelerator commissioning and accelerator physics studies using the LHC. The first beam collisions at LHC are anticipated in the fall of 2009, and HEP is contributing to the first phase of planned upgrades of the accelerator. While the future trajectory of the worldwide HEP program has an emphasis on the energy frontier, the proposed long-range program will provide the U.S. with a balanced and diverse array of world-leading efforts, including new facilities to ensure continued U.S. leadership at the intensity and cosmic frontiers of exploration, such as intense particle beams to probe rare and subtle particle interactions, or ground and space-based observatories for understanding dark energy and dark matter. Accelerator technology R&D is focused on developing infrastructure and expertise to fabricate and test superconducting radio frequency structures, in view of their potential applicability to many scientific disciplines, and HEP is beginning fabrication of new advanced accelerator R&D facilities to develop new particle acceleration technologies for the future.
