BNLs Synchrotron-radiation Research Hub for Characterizing Detection Materials and Devices for the NA-22 Community

The goal of this project is to obtain and characterize scintillators, emerging- and commercial-compoundsemiconductor radiation- detection materials and devices provided by vendors and research organizations. The focus of our proposed research is to clarify the role of the deleterious defects and impurities responsible for the detectors' non-uniformity in scintillating crystals, commercial semiconductor radiation-detector materials, and in emerging R&D ones. Some benefits of this project addresses the need for fabricating high-performance scintillators and compound-semiconductor radiation-detectors with the proven potential for large-scale manufacturing. The findings help researchers to resolve the problems of non-uniformities in scintillating crystals, commercial semiconductor radiation-detector materials, and in emerging R&D ones.

A survey of imaging systems for materials and objects in containers

Radiation imaging can be useful to evaluate the contents of containers; Passive imaging i.e., gamma sources, neutron sources, hydrogen near to a neutron source. Active imaging i.e., Transmission radiography shows high density material; Neutron coincidences indicate fissionable material; Time of Flight and die-away time are important. These technologies may be most useful in confirming ABSENCE of an item.
