Research Institution

Gamma ray and neutron emitting isotopes can be located and identified with the use of a directional gamma ray and neutron detection system having excellent spectroscopic energy resolution. Segmented germanium gamma-ray detectors are the best detectors for such a system. Recent evolutions in germanium detector technology, imaging techniques, electronics, and cryogenics make such a system viable. Together, these developments provide the foundation for a new breed of commercially available, transportable, germanium detector systems with advanced capabilities. We propose to develop the Spectroscopic Imaging Gamma and Neutron Emission Tracker or SIGNET. The SIGNET will be a portable 40 cm x 40 cm x 20 cm instrument containing a mechanically cooled germanium detector system. The SIGNET will display the identity and direction (position) of different radioisotopes in the vicinity of the instrument. The SIGNET will simultaneously determine the presence and direction of neutron sources! The project will bring together fundamental detector physics capabilities to create a portable user-friendly tool for local and federal authorities to better evaluate suspicious situations involving radioactive material. During phase 1, measurements and calculations will provide a detailed design for a prototype SIGNET instrument. We intend to manufacture these instruments in our fabrication facility.
