Marius Wirtz

Dr. Marius Wirtz serves as Team Leader for Material and Component Qualification at the Institute of Fusion Energy and Nuclear Waste Management (IFN), specifically within the Plasma Physics (IFN-1) department at Forschungszentrum Jülich, one of Europe's largest interdisciplinary research centers. His work focuses on developing and testing materials for nuclear fusion applications, particularly plasma-facing components for next-generation fusion reactors including ITER and DEMO. Based at the Jülich campus in Germany, Dr. Wirtz leads a specialized research team that conducts critical qualification testing for materials destined for extreme fusion environments.

Dr. Wirtz's research primarily focuses on plasma-facing materials for nuclear fusion, with special emphasis on tungsten-based components. His work spans thermal shock testing, high heat flux performance, material qualification, and component design for fusion reactors. Key areas include:

• Tungsten and tungsten composites for divertor applications
• Thermal fatigue and shock resistance of plasma-facing materials
• Materials testing under fusion-relevant conditions
• Development of advanced manufacturing techniques for fusion components
• Post-mortem analysis of materials exposed to plasma environments
• Repair technologies for damaged plasma-facing components

Analysis of Dr. Wirtz's recent publications reveals a strong focus on tungsten-based materials for fusion applications, particularly for divertor components in tokamaks and stellarators. His work addresses critical challenges in thermal management, erosion resistance, and component lifetime under extreme fusion conditions. A significant portion of his research involves testing materials at facilities like WEST, JUDITH 2, and OLMAT to simulate ITER and DEMO operating conditions, with particular attention to tungsten fiber-reinforced composites and innovative manufacturing approaches.

Dr. Wirtz leads the Material and Component Qualification team within the Plasma Physics department at Forschungszentrum Jülich. His team utilizes specialized testing facilities including high heat flux test beds, plasma exposure devices, and advanced materials characterization equipment. They collaborate closely with other Jülich institutes and international fusion research centers to develop and qualify materials for next-generation fusion reactors. His work directly supports major international fusion initiatives including EUROfusion, the German Federal Ministry of Education and Research, and collaborations with ITER, WEST, and Wendelstein 7-X.
