Wendelstein 7-X: Gigajoule energy turnover generated for eight minutes

The Greifswald nuclear fusion experiment has achieved its goal of an energy turnover of 1 gigajoule in 2023, surpassing expectations with 1.3 gigajoules. The experiment also set a new record for discharge time, maintaining the hot plasma for eight minutes. The completion work done in the past three years upgraded the heating system, allowing for twice as much power to be coupled into the plasma. The researchers at the Max Planck Institute for Plasma Physics aim to explore higher energy values while taking steps to avoid damaging the facility. The goal is to increase the energy turnover to 18 gigajoules and maintain plasma stability for half an hour. The experiment utilizes magnetic fusion to generate energy by fusing atomic nuclei.
