Fusion devices at IPP

Important research devices of IPP at Garching and Greifswald from the seventies of last century till today


Max-Planck-Institute for Plasma Physics is the world's only fusion centre investigating devices of both the tokamak and stellarator types. This has allowed direct comparison since the early seventies.

Today IPP is running the ASDEX Upgrade tokamak at Garching and the Wendelstein 7-X stellarator at Greifswald.
