Christian Linsmeier

Prof. Dr. Christian Linsmeier is a Director at the Institute for Fusion Energy and Nuclear Waste Management - Plasma Physics (IFN-1) at Forschungszentrum Jülich GmbH and a Professor of Physics and Astronomy at Ruhr University Bochum. His work focuses on plasma-material interaction (PWI), surface processes in fusion devices, and advanced materials for extreme environments.

Education:

• 1982: Abitur (Mathematics-Natural Sciences), Gymnasium Vaterstetten
• 1983–1989: Diploma in Chemistry (Ludwig-Maximilians-University Munich)
• 1989–1990: Diploma thesis at Max Planck Institute for Plasma Physics (Garching)
• 1990–1994: PhD at Max Planck Institute for Plasma Physics and TU Munich
• 2010: Habilitation (TU Munich): "Surface Chemistry of Fusion First Wall Materials"

Research interests include developing materials (e.g., alloys, composites) for fusion reactor components exposed to extreme thermal and particle fluxes. He coordinates EU-funded projects like ExtreMat and FEMaS, and leads groups in plasma-facing materials and plasma edge/wall physics. His experimental work involves large-scale facilities (JET, ASDEX Upgrade, Wendelstein 7-X) and linear plasma systems.

Labs/Facilities: Operates labs for cyclic and steady-state thermal loading of components, including neutron-exposed and toxic materials. Uses spectroscopic methods and numerical modeling for plasma-wall interactions.

Roles and Commitments:

• Chairman of Gauss Fusion GmbH's Strategic Board (2024)
• Member of Bavarian Expert Commission for Nuclear Fusion (2024)
• EFDA Assessment Group for DEMO Structural Materials (2012–)
• Topic Speaker for Plasma-Wall Interaction in Helmholtz Fusion Program (2016–)
