OBJECTIVE: Development of a deployable neutron spectrometer for the prompt identification of materials by exploiting both spontaneous and stimulated neutron emissions. DESCRIPTION: The Defense Threat Reduction Agency (DTRA) seeks the means for extending the identification of materials to neutron spectroscopy for field applications. This solicitation seeks innovative approaches to achieve this capability in support of the DOD effort in countering terrorism, counter-proliferation and non-proliferation. Neutrons are notoriously difficult to shield and/or mask and could potentially serve as a preferred method to detect and identify fissile and special nuclear materials (SNM). However, neutron detection has traditionally been conducted using sensors which are of little benefit in an adverse environment being unwieldy, fragile, and providing little or no information about neutron energy. This solicitation will support the development of a portable neutron spectroscopy instrument capable of performing real time analysis of the data. The successful candidate sensor technology will be sufficiently rugged, lightweight and easy to use so that it may be operated effectively in typical DoD mission environments. The minimum energy resolution of this instrument will allow discrimination between neutrons emitted from fissile and other man-made radiological materials and neutrons to include background neutrons from cosmogenic sources. The time resolution shall also allow for a clear discrimination of prompt and delayed neutrons from nuclei undergoing fission. PHASE I: Develop the conceptual design of a neutron sensor that: o Can perform neutron spectroscopy with the energy resolution necessary to discriminate between fissile and other neutron emitting materials o Can perform clear time discrimination between prompt and delayed neutrons. o Weighs no more than 30 lbs o Can be battery operated for up to 8 hours Perform laboratory testing of any critical items. PHASE II: Manufacture a prototype device which can be evaluated in a laboratory environment. Compare the performance of the neutron spectrometer against existing standards. PHASE III DUAL USE APPLICATIONS: While the DoD requirement for field ruggedness and adverse operating environments is unique, neutron spectroscopy is relevant to both medical and industrial applications. Examples of medical applications of neutron spectrometers are, when used in conjunction with a neutron source, uses in study of soft material containing water and fast neutron therapy. Commercial applications include neutron radiography of structures. REFERENCES: 1. Ambrosi, R.M., Watterson, J.I.W., et al.
