Detailed study of high-temperature superconducting magnets built by MIT and Commonwealth Fusion Systems confirms they meet requirements for an economic, compact fusion power plant. In the predawn hours of September 5, 2021, engineers achieved a major milestone in the labs of MIT's Plasma Science

British and Swiss scientists have developed a 3D imaging technique that allows them to observe complex behaviours in magnets, including fast-moving waves and "tornadoes" thousands of times thinner than a human hair. Writing in the journal Nature Nanotechnology, they say the technique, called time-resolved magnetic laminography, could be used to understand and control the behaviour of new types of magnets for next-generation data storage and processing.
