At DIFFER, a dedicated experiment has been built to see how the wall of a fusion reactor will stand up to the plasma conditions in the future fusion reactor ITER. Magnum-PSI is the first device to recreate all the relevant plasma parameters in one easily accessible device.
Fusion reactors of the tokamak type feature intense hot plasmas hitting the reactor wall near the so-called divertor - the helium exhaust. Understanding the interactions between the plasma and this surface is of vital importance to make
