Magnum-PSI is the main research facility in the DIFFER PSI-Lab. This linear plasma generator is the only laboratory experiment in the world capable of producing the extreme conditions near the wall of the ITER reactor and future fusion reactors.
Magnum-PSI was developed to study the material aspects in fusion reactors. However, as the facilities offer a world-wide unique combination of plasma intensity (particle and heat fluxes, as well as fluency), the facilities are relevant to study any high intensity plasma-wall interaction system. The diagnostic capability of the facilities aims at detailed studies of plasma-wall interaction process and material studies.
In Magnum-PSI, a cascaded arc plasma source produces a hot, dense plasma which is guided to the target by a superconducting magnet. A multitude of diagnostics is employed to analyse the plasma and the wall material during and after exposure. This includes a newly installed Ion Beam Facility, which uses a 3.5 MV ion accelerator to investigate (sub)surface material properties and processes of energy-related materials.
