Creating energy the way the sun and stars do — through nuclear fusion — is one of the grand challenges facing science and technology. What’s easy for the sun and its billions of relatives turns out to be particularly difficult on Earth. On Earth, scientists must generate, confine and sustain a superhot gas called plasma — heated to 10 times the temperature of the center of the sun — to cause a fusion reaction. Although terrestrial plasmas can be confined magnetically, what materials can withstand near such high temperatures and the relentless impact of energetic neutrons? That question is central to the development of economical fusion power plants to provide abundant and carbon-free energy. Scientists at the Department of Energy’s Oak Ridge National Laboratory have been working with Japanese scientists under the Japan-U.S. Fusion Cooperation Program for decades to determine the answer.
