title: Fissile material detection using a prompt fission neutron chamber system.
abstract: The calculations supporting the design of a chamber system to detect and verify fissile material in items such as mail packages or luggage are described. Stimulated neutrons from fission are separated from those produced by the system 14 MeV neutron generators by time delay. The proposed system design has a chamber volume of 60x60x90 cm. It is anticipated that at least 1g of fissile material could be detected in as little as 5s of interrogation.
