A team of physicists and engineers at Princeton Plasma Physics Laboratory built a twisting fusion reactor known as a stellarator that uses permanent magnets, showcasing a potentially cost-effective way of building the powerful machines. Their experiment, called MUSE, relies on 3D-printed and off-the-shelf parts.
The Korea Institute of Fusion Energy has installed a new diverter in the KSTAR tokamak, allowing the artificial sun to sustain high-ion temperatures exceeding 100 million degrees Celsius for longer.
