The Gas Dynamic Trap as Neutron Source for Material Irradiations

An evaluation is presented of the gas dynamic trap (GDT) mirror machine as intense neutron source for fusion material test irradiations. This includes an assessment of the neutronics characteristics of the GDT as compared to future fusion reactor systems (ITER, Demo) and the IFMIF neutron source as well as a detailed design of a helium-cooled test assembly elaborated for the largest of the two material test zones taking proper account of neutronics, thermal-hydraulic and mechanical aspects.
