PHYSICS $193,310,000The FY 2003 Budget Request for the Physics Subactivity is $191.31 million, a decrease of $2.57 million, or -1.3 percent, from the FY 2002 Current Plan of $195.88 million. (Millions of Dollars)
The Physics Subactivity (PHY) supports fundamental research in a broad range of physical phenomena, including support in: atomic, molecular, optical, and plasma physics; elementary particle physics; gravitational physics; nuclear physics; particle and nuclear astrophysics; and theoretical physics. Physics also supports interdisciplinary research, including: biophysics, complex systems, turbulence, and other developing interface areas associated with the core disciplines, for example the interface with information technology. The impact of physics research extends far beyond physics as a result of the discovery of new phenomena and the development of new techniques and basic tools that advance other fields, e.g., laser technology, biomedical technology, information technology, nanotechnology, energy science, including nuclear science, and many other techniques used in high technology industries. Typical awards include funding for faculty salary support, graduate students, post-doctoral associates, instrumentation development, and other research needs. PHY supports an increasingly vigorous effort in the integration of research and education, including support of the Research Experience for Undergraduates (REU) and Research at Undergraduate Institutions (RUI) programs, the Faculty Early Career Development Program (CAREER), and important and innovative new outreach efforts aimed at improving links to K-12 teachers and students. The REU program continues to be very successful at reaching underrepresented minorities and women. The Physics Subactivity provides support for a large part of university-based research in the physics sub-disciplines, ranging from nearly 100 percent for gravitational physics to 30-40 percent for the other physics programs. The scope of support ranges from small, single-investigator awards for research based at the awardee's home institution, to awards to major user groups with principal responsibility for experiments at major national or international user facilities. PHY also supports centers and institutes and national user facilities in elementary particle, nuclear, and gravitational physics. The user facilities represent important elements of the national infrastructure for certain subfields: in elementary particle physics, the Cornell Electron Storage Ring (CESR); in nuclear physics, the Michigan State University National Superconducting Cyclotron Facility (NSCL); and in gravitational physics, the Laser Interferometer Gravitational-Wave Observatory (LIGO). Center activities include: support for Physics Frontiers Centers, the first class of which include centers in the following areas: cosmological physics, gravitational physics, coherent ultrafast optical science, and the structure and origin of matter (particle and nuclear physics), the latter at an HBCU; and a new Science and Technology Center in biophotonics, applying new techniques developed in atomic, molecular and optical physics to studies of biological systems. The Physics Subactivity supports major infrastructure within atomic, molecular, optical, and plasma (AMOP) physics such as the new Physics Frontiers Center `Frontiers of Optical, Coherent and Ultrafast Science' (FOCUS) at the University of Michigan, the Center for Ultracold Atoms at MIT, and the University of Colorado laboratory for atomic, molecular, and optical physics (JILA). Physics tools have had an enormous impact on national security, from nuclear technologies and laser-based guidance and control systems, to radiation-hardened electronics and precision clocks for GPS (even including general relativity corrections). In the future, research in quantum information science will contribute centrally to the science of encryption and to the sorting and correlating of massive information bases - keys to future intelligence activities. The Physics Subactivity oversees a construction project funded through the Major Research Equipment and Facilities Construction (MREFC) Account - the Large Hadron Collider (LHC) ATLAS and CMS detectors. Construction funding for the LHC detectors, begun in FY 1999, continues in FY 2003 (see the MREFC Account for additional information). LIGO, which was also funded through the MREFC Account, is expected to be fully operational in FY 2003, with all interferometers operating in coincidence (the 2- and 4-km interferometers at Hanford and the 4-km interferometer at the Livingston site). The "quantum realm" continues as a broad area within the Physics Subactivity where there has been important progress. AMOP grantees won the 2001 Nobel Prize for Physics for achieving Bose-Einstein condensation in dilute gases, and for studies of the properties of condensates, studies that may bring revolutionary applications to nanotechnology. The FY 2003 Budget request for PHY includes:
