Max Planck Institute for Plasma Physics, Greifswald is home to Wendelstein 7-X. It is the world’s largest stellarator, will confine plasma with temperatures of up to 100 million degrees and discharges lasting up to 30 minutes, and will be key to investigating a stellarator’s suitability as possible design for a future fusion power plant.
Plasma-wall interaction is one of the most critical issues with respect to the performance and availability of ITER and future fusion reactors. Linear devices Magnum PSI, PSI-2 and JULE-PSI make excellent test beds to investigatie specific questions of plasma-wall interaction and test plasma-facing materials.
