The advanced stellarator Wendelstein 7-X, housed at the IPP Greifswald campus began operations in December 2015. Wendelstein 7-X is an engineering and modelling feat, not only because it is the world’s largest stellarator with a diameter of around 16 meters but also because it is expected to be able to confine the 100-million-degree Celsius plasma discharges for up to 30 minutes. Among other things, EUROfusion researchers are investigating the device to determine the suitability of a stellarator concept for a power plant. Visit the IPP webpage on Wendelstein 7-X to learn more.
