Concept design of a transportable, high-resolution, neutron radiography system

An initial design for a high-resolution, transportable neutron radiography system concept has been developed. The system requirements taken to be a thermal neutron flux; of 10(6) ni(cm(2)-sec) with a LID of 100. The approach is to use an accelerator-driven neutron source, with a radiofrequency quadrupole (RFQ) as the primary accelerator component Initial concepts for all of the major components of the system have been developed, and selected key parts, such as the RFQ and target-moderator subsystems, have been examined further. The concept features a compact trailer-mounted configuration during transport, with deployable neutron production and radiographic imaging assemblies. An overview of the system design is presented, together with brief descriptions of the concepts for each of the major subsystems. Studies completed for the RFQ and moderator are summarized, and issues identified during the course of the work are discussed.
