The Role of Enabling Technology Research in a Science-Based Fusion Energy Research Program Charles C. Baker Virtual Laboratory for Technology, University of California - San Diego, 9500 Gilman Drive, La Jolla, CA 92093-0420 858-534-4971 (phone), 858-534-5440 (fax) cbakervlt.ucsd.edu The mission of the US Fusion Energy Sciences Program is to advance plasma science, fusion science, and fusion technology–the knowledge base needed for an economically and environmentally attractive fusion energy source. In support of this overall mission, the Enabling Technology Program in the US incorporates both near and long term R&D, contributes to material and engineering sciences as well as technology development, contributes to spin-off applications, and performs global systems assessments and focused design studies. This work supports both magnetic and inertial fusion energy concepts. The Enabling Technology research mission is to contribute to the national science and technology base by developing the enabling technology for existing and next-step experimental devices, by exploring and understanding key materials and technology feasibility issues for attractive fusion power sources, by conducting advanced design studies that integrate the wealth of our understanding to guide R&D priorities and by developing design solutions for next-step and future devices. The Enabling Technology Program Plan is organized around five elements: Plasma Technologies, Fusion (Chamber) Technologies, Materials Sciences, Advanced Design, and IFE Chamber and Target Technologies. This presentation will highlight the role of and implications for enabling technology research in a science-based fusion energy sciences program.
