For studying neutronic and nuclear characteristics of the projected International Fusion Materials Irradiation Facility (IFMIF), a saturation thick target of natural lithium was irradiated with 40 MeV deuterons from the Karlsruhe Isochronous Cyclotron. The resulting neutron spectrum and yield were measured by multi-foil activation. The production rates of the radionuclides tritium and beryllium-7 in the lithium were also measured. They are (6.85 g #+-# 7%) tritium and (1.85 g #+-# 12%) Be-7 per IFMIF full power year at 40 MeV and 250 mA; these values supersede preliminary results given earlier. Further, samples of two different steels, pure vanadium, and a vanadium alloy were activated in the neutron field, and specific activities of many r...
