The FY 1985 request for Operating Expenses will permit an overall utilization level of the High Energy Physics accelerator facilities at about 55%, somewhat above the FY 1984 level. The request also provides continuing support for university and laboratory based research groups including accelerator experiments, non-accelerator experiments, and theoretical research. There will be continuing accelerator R&D activities at Fermilab and SLAC in support of ongoing construction projects. The FY 1985 request for Operating Expenses also will provide for preliminary R&D studies for the next generation particle accelerator designated the Superconducting Super Collider (SSC). Construction of such a new facility was recommended by the High Energy Physics Advisory Panel (HEPAP). Specifically, HEPAP recommended as highest priority "the immediate inftiation of a multi-Tev high luminosity proton-proton collider project with the goal of physics experiments at the earliest possible date." The SSC would provide a research capability in an unexplored domain for which there are no existing or planned facilities anywhere in the world and in which there is strong expectation of major research breakthroughs. The Department has evaluated the HEPAP recommendation and deci to initiate an R&D program at various locations in FY 1984 to investigate key issues associated with construction of such a accelerator. The major emphasis in FY 1984 is on superconduc magnet R&D and on developing a reference design with a cost estimate based on credible assumptions about possible achieve in the R&D program. In FY 1985, preliminary R&D for the SSC focus on development and evaluation of technical options for magnets and other accelerator components, development and validation of cost saving designs and fabrication techniques, consideration of accelerator design alternatives and trade-of and cost optimization studies. The FY 1985 Capital Equipment request of $65.4 million provide substantial increase above the FY 1984 level in order to meet of the major needs associated with implementation of research programs using the major new research capabilities being provi by the Tevatron I and Tevatron II projects at Fermilab and the Stanford Linear Collider (SLC) at the Stanford Linear Accelera Center. This increase in Capital Equipment funding in FY 1985 essential for the effective utilization of the U.S. High Energ Physics facilities and for the health of the U.S. High Energy Physics program for the remainder of the 1980's. The request for Capital Equipment gives priority to Fermilab f the new secondary beam lines and detector systems needed to implement the 1000 GeV research program associated with the Tevatron II fixed target program and for work on detectors need for the Tevatron I proton-antiproton colliding beam research program. Priority is also given to SLAC for work on detectors electron-positron colliding beam research at the SLC; to the university program to meet the needs of experiments at the U.S. laboratories and at the Large Electron Positron (LEP) facility a the CERN Laboratory in Geneva, Switzerland; and for non-accelera experiments. In addition to programmatic equipment needs, the High Energy requirements for all DOE programs at the Brookhaven National The A total of $114.8 million in Construction funding for High Energy Physics projects is requested in FY 1985. The projects are listed in Table 3. A major portion of this request is for continued Construction of the Stanford Linear Collider ($60.5 million). primary goal of this project is to develop and demonstrate the technical feasibility of using linear accelerators with precisely Controlled, high intensity and highly focused beam pulses to provide high rates of electron-positron collisions at energies far beyond those that will be affordable for circular colliders. SLC also will give U.S. physicists early access to the important physics which can be studied with copious production of the z° particle. The request also provides for completion of the Tevatron II project at Fermilab ($12.8 million) and continuation of Tevatron I ($21.3 million) at Fermilab. The Funds are requested for Accelerator Improvement Projects ($10.0 million), which are critical on an annual basis to maintain the scientific effectiveness and the operating reliability and efficiency of the accelerator and colliding beam facilities. request also provides for an improved level of General Plant Projects ($10.2 million). Within the GPP request, emphasis is placed on the needs at BNL, since the High Energy Physics program provides funding for the general purpose needs of all DOE programs at this laboratory. NUCLEAR PHYSICS Nuclear knowledge, techniques, instruments, and applications pervade American society. These serve as the basis for our national defense strategy, for therapeutic and diagnostic medical applications, for the generation of electricity with nuclear reactors (fission now and fusion in the future), and for a large and diverse array of applications in industry. The behavior of nuclei and nuclear matter determine the physical properties of our universe--from its creation from a primordial "soup" of energy and elementary particles, to the reactions which power our sun, to the makeup of our planet. Thus, basic nuclear research is both a central component in our Nation's long-term investment in its technological future and an essential foundation to any basic understanding of the world about us. The Nuclear Physics program is a comprehensive program of interdependent experimental and theoretical investigations of atomic nuclei. The goal of the program is to understand the interactions, properties, and structures of atomic nuclei and nuclear matter at an elementary level and to gain knowledge of the fundamental forces of nature by using nuclei as a proving ground. |
