IFMIF, International Fusion Materials Irradiation Facility

A fusion relevant neutron source is a more than three decades long pending step for the successful development of fusion energy.

In DEMO, like in future fusion power plants, the deuterium-tritium nuclear fusion reactions will generate neutron fluxes in the order of 1018m-2s-1 with an energy of 14.1 MeV that will collide with the first wall of the reactor vessel, which provides the physical boundary for the plasma and contributes to the thermal and nuclear shielding of the external machine components such as the superconducting magnets.
