Characterization of neutron imaging facility at Penn State Breazeale Nuclear Reactor

Characterization experiments of a new neutron imaging facility at the Radiation Science and Engineering Center (RSEC – NIF) that utilizes the Penn State Breazeale TRIGA reactor were performed to assess the imaging system. It was verified that the RSEC – NIF corresponds to a Category I facility by ASTM designation of quality. Obtained characterization results allow the use of direct and indirect methods of neutron radiography and tomography techniques utilizing conventional films and modern phosphorous plates. This paper describes the details of characterization experiments as well as preliminary results of neutron tomography capabilities of the newly built system.
