Portable API Neutron Generator

Advanced neutron imaging with superior temporal discrimination and spatial localization of radiation signatures is needed to counter nuclear threats and mission spaces encountered by the NNSA.Nextgeneration associated-particle imaging (API) with emphasis on high-speed, human portability and multimodal interrogation capability, including transmission radiography and induced emission (fission, elastic scatter, inelastic gamma) imaging, is required.The problem is being addressed by: (1) increasing the output of a neutron generator while simultaneously improving its spot size for sharper imaging, and (2) coupling with high-speed electronics and detection elements in an end-mounted target API configuration for end-user application flexibility.Phase I demonstrated spot size, output and pathway for API integration—leveraging recent DARPA investment through the Intense Compact Neutron Source program.Phase II will integrate API detectors onto an nGenTM-400 human-portable sealed generator for field testing with National Laboratory collaboration for technology readiness assessment and comparative testing.The overall approach takes advantage of Starfire’s grounded target for maximum imaging utilization.Beyond national security needs, the technology has immediate application for commercial cargo manifest screening for packages, parcels and unit load air cargo inspection, as well as customs and border patrol applications for illicit drugs, explosives and contraband materials.Industrial clients could also benefit from another imaging radiography modality for non-destructive test and evaluation.
