Neutron production in a Pb/U-setup irradiated with 0.7–2.5 GeV protons and deuterons

A thick Pb-target with a U-blanket surrounded by a polyethylene moderator was irradiated with 0.7–2.5 GeV proton and deuteron beams. Neutron production was studied with activation detectors. Neutron multiplicity was determined using a modified form of the water-bath/activation-foil method. The experimental results were compared with Monte Carlo simulations performed with the MCNPX code (INCL4+ABLA). Neutron multiplicities on the Pb/U-setup were also compared with data measured on thick Pb-target irradiated with 0.1–4.5 GeV proton beams to date.
