IPP

Intelligence Summary: Max Planck Institute for Plasma Physics (IPP)

Node Identity: IPP (Max-Planck-Institut für Plasmaphysik) is Germany's premier plasma physics research institution and the world's only fusion center simultaneously investigating both tokamak and stellarator confinement concepts. Founded in 1960 and incorporated into the Max Planck Society in 1971, IPP operates from two sites — Garching (near Munich) and Greifswald — hosting the ASDEX Upgrade tokamak and the Wendelstein 7-X stellarator respectively. IPP serves as coordinator of the EUROfusion consortium and hosts the Programme Management Unit, making it the administrative nerve center for all European fusion research.

Strategic Relevance: IPP's dual-track approach gives Germany unparalleled plasma physics expertise spanning both the mainstream tokamak line (ITER-relevant) and the alternative stellarator line (W7-X). The stellarator is explicitly designated as Europe's "long-term alternative or backup strategy for the tokamak" in the European fusion roadmap. The superconducting magnet technology, plasma control systems, and divertor physics developed at IPP have clear dual-use potential — the same plasma confinement and control expertise applicable to energy production is directly relevant to advanced plasma weapons concepts. IPP's coordination of EUROfusion gives Germany institutional influence over the entire European fusion research agenda far exceeding its financial contribution share.

Technical Focus / Capabilities: IPP's historical achievements include discovery of the H-mode (high-confinement regime) in the ASDEX tokamak in 1982 — a foundational result for ITER design. ASDEX Upgrade (operational since 1991) resumed operations in November 2024 after a two-year maintenance that installed a new upper divertor with internal coils (Doi and Doa), a high-capacity cryopump, and state-of-the-art diagnostics, enabling exploration of alternative divertor configurations for ITER and DEMO with up to 19 MW heating power. W7-X achieved a world record triple product in 43-second sustained plasma discharges (May 2025), surpassing tokamak records for long-duration plasmas, with 1.8 GJ maximum heating energy input and 8.5 MW microwave heating power.

Network Linkage: IPP is funded by BMBF, operates both W7-X and ASDEX Upgrade, coordinates EUROfusion (hosting the PMU), contributes to ITER through plasma control and neutral beam heating, and develops the HELIAS reactor studies. It maintains the central position in Germany's fusion network with connections to KIT, FZJ, and international partners through EUROfusion and ITER frameworks.
