After successful recommissioning in autumn 2022, the Wendelstein 7-X stellarator fusion device at Germany's Max Planck Institute for Plasma Physics (IPP) has achieved some significant breakthroughs. In 2023, an energy turnover of 1 gigajoule was targeted, but researchers have now achieved 1.3 gigajoules. Moreover, a new record for discharge time was achieved, with the hot plasma maintained for eight minutes.

Scientists at Germany’s Max Planck Institute for Plasma Physics (IPP) on 25 June reported a new record performance at the Wendelstein 7-X stellerator, which began operation in 2015. Earlier experiments saw the plasma in the reactor achieve higher temperatures and densities than ever before, and now the records have been broken again in a new test with upgraded components. Like the tokamak, the stellarator uses large superconducting magnets to suspend hydrogen plasma and heat it to the temperatures and pressures needed to fuse hydrogen into helium. The Wendelstein 7-X has 50 superconducting magnet coils some 3.5 metres high. However, while the tokamak confines plasma in a doughnut shaped torus, the stellarator traps the plasma in a twisting spiral shape, which is designed to cancel out instabilities in the suspended plasma.
