Here at DIII-D, we have an active collaboration, with multiple institutions looking at the many ways plasma and the vessel wall can interact.”ĭIII-D is the largest magnetic fusion research facility in the United States and is operated by General Atomics for the U.S. “The specific way in which this will be accomplished is still an open unsolved question and a very active area of research worldwide. “Developing robust wall materials is absolutely necessary for economic fusion energy,” said Dan Thomas, Ph.D., a scientific manager at DIII-D who is helping to coordinate the multi-institution effort on these new experiments. ![]() The new approach researchers are testing will leverage an existing component on DIII-D, known as the Small Angle Slot (SAS) Divertor, to minimize tungsten erosion and release into the plasma. However, tungsten is also an impurity for the fusion reaction and can impair performance. ![]() Solutions such as this will be critical to developing practical fusion energy.Ĭurrent fusion power plant designs envision using tungsten as a key component in the reactor vessels because of its high resistance to heat and radiation. San Diego, April 25 – Researchers at the DIII-D National Fusion Facility are preparing to test a new method to enable future fusion power plants to withstand the fierce conditions of heat and particle flow created by the fusion reaction. New approach will test advanced metal divertor configurations
