fusion effort? It is widely agreed in the plasma physics community that the next large-scale step in the effort to achieve fusion energy is to create a burning plasma -- one in which alpha particles from the fusion reactions provide the dominant heating of the plasma necessary to sustain the fusion reaction.

If the United States is interested in the long-term goal of fusion as a source of economical, sustainable energy and not only in the ITER effort, the na tion needs a science program based on some of the existing facilities; a technology program; a computation, simulation, and theory program; and a university program. At a minimum, to capture the benefits of a burning plasma experiment, an augmentation of the U.S.

fusion science program. · The United States should pursue an appropriate level of involvement in the ITER project, which at a minimum would guarantee access to all data from ITER, the right to propose and carry out experiments, and a role in producing the high-technology components of the facility consistent with the size of the U.S.

Participation by the United States in ITER also very effectively leverages the U.S. investment in its own fusion science program.

fusion program. For instance, a technology program without a strong science base, or a science program without a strong technology base, will leave the United States unable to build effectively on the developments coming from more advanced programs abroad as well as from the ITER program.

The roles that university programs play in meeting needs for personnel and in providing new ideas and training opportunities can be ex pected to continue throughout the era of the burning plasma experiment and farther along the path to practical fusion energy. In addition, postdoctoral re search programs at the national facilities provide critical advanced training in detailed fusion science issues.

The balancing process also could be guided by multiyear budget planning that projects funding growth and should involve significant community input. The prioritization process should be organized with three elements of the fusion program in mind: -- To advance plasma science in pursuit of national science and technol ogy goals; -- To develop fusion science, technology, and plasma confinement inno vations as the central theme of the domestic program; and -- To pursue fusion energy science and technology as a partner in the international effort.

Having concluded that the United States is ready to take the next critical step in fusion research, the committee recommends the implementation of a burning plasma experiment through participation in the ITER program as part of a strate gically balanced U.S. fusion program.
