recommended 4 GeV. Shortly thereafter, SURA submitted its second proposal. Argonne National Laboratory, the University of Illinois, the Massachusetts Institute of Technology (MIT), and the National Bureau of Standards (NBS) also submitted proposals. Both Argonne's and SURA's proposals were for 4-GeV accelerators; the other institutions' designs were for lower energies.

During the winter of 1982/83 the NSAC panel on Electron Accelerator Facilities, chaired by Professor D. Allan Bromley of Yale University, reviewed and evaluated the proposals at the request of the NSF and DOE. As part of the deliberations, the panel reconsidered the choice of energy and affirmed the selection of 4 GeV. NSAC endorsed the panel's recommendation to build a facility based on the SURA proposal. In May 1983, SURA submitted a proposal to DOE for preconstruction R&D.

Subsequently the agency and the nuclear physics community have reviewed and consistently reaffirmed the various decisions, including the choice of energy, the priority of an electron machine, and the selection of the SURA proposal. In this process, the new facility was named the Continuous Electron Beam Accelerator Facility (CEBAF). It received its first federal funds in August 1984 to develop the design and to perform architectural and engineering work on the conventional facilities. Federal funding to continue preparing for construction was also provided in FY 1985 and FY 1986.

Summary

CEBAF is the highest priority new construction project for the national nuclear physics program. Enthusiasm among physicists to exploit its capabilities to study the quark structure of the nucleus continues to grow. In preparing for a construction start in FY 1987, the project is on schedule.

By the end of FY 1986 CEBAF will have spent some $13 M of federal, Virginia, and SURA funds. The staff and management structure to begin construction are in place. The facility design is developed, optimized, documented, and thoroughly reviewed. The component prototype program is well underway and has met all milestones and performance specifications to date. Nuclear physicists at CEBAF and around the country are formulating the experimental program and designing equipment.

With Congressional approval, CEBAF will be ready to start construction in FY 1987.

Mr. FUQUA. Thank you, sir.

Dr. Browne.

DR. JOHN C. BROWNE

John C. Browne received his undergraduate education in physics at Drexel University in Philadelphia and received the Ph.D. in nuclear physics from Duke University in 1969. He was a research scientist at Lawrence Livermore National Laboratory from 1970-79. Since 1979, he has been employed at the Los Alamos National Laboratory as a research group leader and head of the Physics Division. He currently is Associate Director for Research at Los Alamos.

STATEMENT OF DR. JOHN C. BROWNE, ASSOCIATE DIRECTOR FOR RESEARCH, LOS ALAMOS NATIONAL LABORATORY, LOS ALAMOS, NM

Dr. BROWNE. Mr. Chairman and members of the subcommittee, I am pleased to have the opportunity to offer my testimony on behalf of our new laboratory director at Los Alamos, Dr. Siegfried Hecker. Your letter of invitation to Dr. Hecker requested testimony addressed to two topics: the Los Alamos National Laboratory proposal to construct a neutron scattering experimental hall and the impact of the fiscal year 1987 budget on the laboratory under several different scenarios. I will focus only on the experimental hall project in this testimony; the other topic is discussed in detail in the written testimony.

As an introduction to this project, I think it is important for the committee to understand the role of basic research at our laboratory. The primary mission of Los Alamos National Laboratory is to be a national resource of scientific, technical, and engineering capabilities focused on the execution of the national security programs of the Department of Energy, principally the development of the nuclear warheads for our Nation's defense.

The basic research activities of the laboratory which are supported primarily by the Department of Energy's Office of Basic-Office of Energy Research are crucial to the success of our laboratory and its primary mission.

Basic research is key to the advancement of technology which directly impacts the quality and performance of our defense developments. Basic research also permits us to recruit outstanding scientists and engineers to our laboratory who provide a core of strength for the defense program to draw upon for the solution of challenging technical problems.

A perfect example of this synergism between basic research and defense activities is represented by the neutron scattering experimental hall project under consideration by this committee today.

This project will utilize the output of the Los Alamos Meson Physics Facility-LAMPF-which was completed in 1972 as a basic research facility for nuclear physics. LAMPF is the highest intensity high energy proton accelerator in the world, producing a 1 milliampere beam of 800 MeV protons. Many of the students, post-docs, and staff who came to LAMPF to perform basic nuclear physics research have been attracted to the scientific and technical challenges of our applied programs and have made outstanding contributions.

Ten percent of the LAMPF proton beam can be diverted on a noninterfering basis to our new proton storage ring which accumulates a long pulse of protons from LAMPF and compresses the beam to a short pulse appropriate for use in neutron scattering for material science studies.

The proton storage ring was funded as a Department of Energy/ Defense program project in fiscal year 1979 at a cost of $21.8 million.

The protons from the storage ring impinge on a target in a shielded crypt in our existing experimental area to create an intense pulse of neutrons which are then culminated through evacuated tubes to a set of experiments. This facility provides the United States with the highest peak intensity source of pulsed neutrons in the world for material science studies.

X-rays or photons as produced by machines like the advanced light source, which Dr. Shirley will discuss, and neutrons are complementary probes of materials, each providing important pieces of the puzzles to be unraveled.

Our intent is to develop our neutron capability for a national materials science user program for universities, industry, and other Government laboratories under the program of the Office of Basic Energy Sciences.

However, our existing experimental space is very cramped to do experiments in an effective manner for a national user program, and at this point, Mr. Chairman, I'd like to show one viewgraph. [Slide shown.]
