Nuclear Fusion: Research for a New Primary Energy Source

We are part of an internationally networked effort to make power plants based on nuclear fusion a reality. We aim to set in motion on earth the process by means of which the sun and other stars produce their energy, thus providing a safe, environmentally friendly energy supply that will be available in the long term.

Plasma-Material Interactions

Our research focuses on the plasma-wall interactions and materials for first walls in a fusion reactor. Extremely high thermal loads occur here that future power plants will have to withstand in continuous load operation if they are to be economically viable. We investigate the materials suited to this purpose and analyse their interaction with the hot fusion plasma, in collaboration with leading fusion experiments all over the world.

Plasma-Wall Interaction - A Key Issue in Progress Towards Fusion Power Plants

Generating energy from fusion requires a plasma with a temperature of 100 million degrees. Strong magnetic fields are used to protect the wall of a fusion device

Lineares Plasma in der PSI-2

Plasma-Wall Interaction in Linear Plasma Devices

The interaction between the plasma and the wall materials in a fusion reactor is a key factor determining the lifetime of the wall components and thus the overall cost-effectiveness of the facility.

Blick auf JUDITH-2

Material tests under very high loads

The emphasis of the research in the high temperature materials laboratory (HML) is put on experiments for the characterization of materials

Wärmeflusstest von Erste-Wand-Komponenten

Plasma-facing Materials

The "first wall" is the name given to the surface of the inner wall of a fusion reactor. This wall is in direct contact with the plasmy and is thus directly affected by the plasma and its constituents.


Theoretical and Computational Fusion Edge Plasma Science

The development of future fusion reactors such as ITER and DEMO, whether as tokamaks or stellarators, requires accurate predictions

Blick in den Stellarator Wendelstein 7-X

Wendelstein 7-X

The world's largest stellarator, Wendelstein 7-X, is running at the Max-Planck-Institute for Plasma Physics in Greifswald.



The large-scale fusion experiment ITER (Latin for "the way") is currently under construction in Cadarache in the south of France as part of an international cooperation


JET ITER-like Wall

Forschungszentrum Jülich designed and constructed a divertor, which is part of the new first wall in the leading fusion experiment, JET - the "ITER-like wall".

The large scale fusion experiment ITER (Latin for "the way") ) is currently under construction in Cadarache in the south of France. ITER is the world’s first fusion reactor



Was the largest fusion experiment at Jülich for 30 years until 2013. The mission of it was to expose the inner wall with heat and particle loads
