Eight European fusion devices, one common goal

EUROfusion Devices

The flagship device of the European fusion programme is JET, the Joint European Torus, which is jointly used and financed by all European laboratories. Besides JET, EUROfusion has access to other experiments that contribute directly to the Roadmap missions.


JET, the Joint European Torus, is EUROfusion's flagship device. It is housed at the Culham Centre for Fusion Energy, UK. JET is currently the largest tokamak in the world and the only one capable of operating with a Deuterium-Tritium fuel.


collage Medium Size Tokamak (MST)
Medium-Sized Tokamaks

The Medium Size Tokamak (MST) project enables experiments that cannot be done on JET, complements and confirms JET results and broadens the experimental database. ASDEX-Upgrade, TCV, MAST-Upgrade and WEST are the devices that are used in the MST experiments



Max Planck Institute for Plasma Physics, Greifswald is home to Wendelstein 7-X. It is the world’s largest stellarator, will confine plasma with temperatures of up to 100 million degrees and discharges lasting up to 30 minutes, and will be key to investigating a stellarator’s suitability as possible design for a future fusion power plant.


Linear Devices

Plasma-wall interaction is one of the most critical issues with respect to the performance and availability of ITER and future fusion reactors. Linear devices Magnum PSI,  PSI-2 and JULE-PSI make excellent test beds to investigatie specific questions of plasma-wall interaction and test plasma-facing materials.
