1 Research in Physics Why? Who pays for it? How do you decide what to do? Professor Ani Aprahamian University of Notre Dame

2 The US economy depends on Science scientific and technical innovations they produce Economic studies conducted even before the informationtechnology revolution have shown that as much as 85% of measured growth in US income per capita was due to technological change.

3 WHO PAYS FOR IT? National Science Foundation Department of Energy NASA NIH NIST Others

6 The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense " With an annual budget of about $6.06 billion, we are the funding source for approximately 20 percent of all federally supported basic research conducted by America's colleges and universities. In many fields such as mathematics, computer science and the social sciences, NSF is the major source of federal backing.

11 The Department of Energy is the single largest Federal government supporter of basic research in the physical sciences in the United States, providing more than 40 percent of total Federal funding for this vital area of national importance. It oversees, and is the principal Federal funding agency of, the Nation s research programs in high-energy physics, nuclear physics, and fusion energy sciences. Such a diverse research portfolio supports tens of thousands of principal investigators, post-doctoral students, and graduate students who are tackling some of the most challenging scientific questions of our era.

12 Research and Development DOE manages fundamental research programs in basic energy sciences, biological and environmental sciences, and computational science and is the Federal Government s largest single provider of funds for materials and chemical sciences. Ensuring the supply of radio isotopes Radio Isotopes have become key agents in the diagnosis and effective treatment of various cancers, heart disease and other medical problems. DOE programs ensure the availability of an adequate supply of medical and research isotopes, which is essential to the Nation s health care system. Research in environmental sciences The Department conducts research in climate change, geophysics, genomics, life sciences, and science education, as well as scientific research in the areas of fossil energy and environmental science.

14 So, How are priorities set???????? Federal agencies get advice

15 National Science Academies National Academy of Engineering National Institutes of Health National Research Council The Board on Physics and Astronomy is the Academies' principal forum for issues connected with the fields of physics and astronomy.

16 What is dark matter? What is dark energy? How did the universe begin? Was Einstein right about gravity? How have ν shaped the universe? What are nature s most energetic particles? Are protons stable? Are there new states of matter at exceedingly high density/energy? Are there additional dimensions? How were elements Fe to U made? Is a new theory needed at the highest energies and EM Fields?

18 Get advice from different bodies.. Nuclear Science Advisory Committee NSAC is an advisory committee that provides official advice to the Department of Energy (DOE) and the National Science Foundation (NSF) on the national program for basic nuclear science research. High Energy Physics Advisory Panel The High Energy Physics Advisory Panel (HEPAP) has advised the Federal Government on the national program in experimental and theoretical high energy physics (HEP) research since its inception in 1967.

19 NSAC Long Range Plan We recommend a targeted program of experiments to investigate neutrino properties and fundamental symmetries. These experiments aim to discover the nature of the neutrino, yet-unseen violations of time-reversal symmetry, and other key ingredients of the New Standard Model of fundamental interactions. Construction of a Deep Underground Science and Engineering Laboratory is vital to U.S. leadership in core aspects of this initiative. DOE and NSF charged Nuclear Science Advisory Committee in July 2006 to develop a long range plan for the next decade. Report delivered on December 2007

20 PARTICLE PHYSICS PROJECT PRIORITIZATION PANEL (P5) The Particle Physics Project Prioritization Panel (P5) is a sub-panel of the High Energy Physics Advisory Panel (HEPAP). Charged in Jan 2008 by NSF and DOE with recommending a 10-year road map for particle physics. The three frontiers of research in particle physics, as expressed by the P5 Panel, which form an interlocking framework that addresses fundamental questions about the laws of nature and the cosmos.

21 P5 RECOMMENDATIONS Report approved by HEPAP at their May 2008 meeting in Washington. From Executive Summary: The panel recommends a world-class neutrino program as a core component of the US program, with the long-term vision of a large detector in the proposed DUSEL laboratory and a high-intensity neutrino source at Fermilab. The panel endorses the importance of a deep underground laboratory to particle physics and urges NSF to make this facility a reality as rapidly as possible. Furthermore the panel recommends that DOE and NSF work together to realize the experimental particle physics program at DUSEL. Fermilab/DUSEL program recommended by P5 constitutes the primary element of the on-shore U.S. particle physics program during the coming decade.
