Harnessing the power that makes the sun and stars shine could be made easier by powerful magnets with straighter shapes than have been made before. Researchers linked to the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have found a way to create such magnets for fusion facilities known as stellarators. Such facilities have complex twisted magnetic coils, compared with the straight up-and-down coils in more widely used tokamak facilities, and […]
