On Wednesday 21 March, the research facility Magnum-PSI
at DIFFER (Dutch Institute for Fundamental Energy Research) set a new world record for longest exposure of a material to the harsh plasma conditions in future fusion reactors. Magnum-PSI exposed tungsten wall components to the equivalent of a full year of high power fusion operations in the future ITER
reactor, 50 times more than the previous record. The exposure took only 18 hours to complete and shows Magnum-PSI's unique capability to investigate how materials hold up under a sizeable part of their lifetime in ITER.
