The Max Planck Institute for Plasma Physics (IPP) announced yesterday that it is developing 2-MW gyrotrons to be used as the main plasma heating system of the Wendelstein 7-X (W7-X).

W7-X, located at IPP, is currently the largest superconducting stellarator facility in the world. The project conducts research aimed at filling key knowledge and technology gaps for developing a stellarator-based power plant.
