Wendelstein 7-X Stellarator Achieves Record-Breaking Plasma Duration

Germany's Wendelstein 7-X stellarator has set a new world record during its OP 2.3 campaign, achieving a high fusion triple product value in its plasma for 43 seconds. This milestone signifies a significant step towards a future fusion power plant. The record was made possible through international collaboration, notably a pellet injector from Oak Ridge National Laboratory, and diagnostic equipment from other labs in Europe and the US. Beyond the triple product, the experiment also achieved milestones in energy turnover and plasma pressure.
