The X-ray source, which included a tungsten target for bremsstrahlung, was originally fabricated for on-site nondestructive inspections for infrastructures such as bridges, expressways and tunnels. Attachment of a photo-neutron target to this X-ray source allows a new mobile neutron source. Main applications of this neutron source are on-site moisture detection in infrastructures, and nuclear materials measurement in fuel debris for decommissioning Fukushima nuclear power plants. Our approach also realizes a mobile X-ray/neutron hybrid source system in the future. The beryllium was employed as target material since it had especially small threshold energy for the photo neutron production. We have developed a 60-cm-cube target station by combining a beryllium block, a graphite reflector, a polyethylene moderator, a boric acid resin layer (neutron shied), and a lead layer (gamma-ray shield). This presentation will report a pilot experiment of neutron generation and discuss the results compared to a Monte Carlo simulation.
