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

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.

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

Stellarators

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.

JT-60SA

The JT-60SA tokamak in Naka, Japan is a joint Japanese-European fusion device resulting from their international science and technology collaboration known as the “Broader Approach”. JT-60SA is the most powerful fusion device to date and will study plasma operations in preparation for ITER and DEMO.
