At the completion of the research and development effort a Li foil multi-wire proportional counter (MWPC) neutron detector with more than 625 cm^2 of active area will be included in a portable radiation detection system. The system is expected to have an intrinsic thermal neutron detection efficiency of 55% or greater and gamma-ray rejection ratio (GRR) of 1.0x10^-8 or better. A gamma-ray spectrom ...

This STTR will focus on demonstrating feasible methods to integrate additive manufacturing (AM) structure, processing, and property-geometry modeling methods that will facilitate the qualification and certification of AM-fabricated 4340 steel alloy parts and enable their rapid deployment. During the Phase I feasibility demonstrations the contractor and Research Institute (RI) will define and devel ...

Despite recent advances in Ebeam additive manufacturing, the parts produces by such processes often are inferior to those produced by traditional machining methods. Due to the complexity of the process and the multiple physical phenomena that interact, it is difficult to predict and control the properties and underlying microstructure of the resulting component. In addition, the rapid and repeated ...

The technical requirements for the simulation of a helicopter towing an aircraft while performing a MAD mission are identified. Several technical solutions to achieve high stability during the mission are presented. In Phase I, a simulation will be set up to begin trade studies on the proposed mission. Also, if needed, flight tests will be conducted in Phase I, as proof-of-concept validation. In P ...

The Phase I research will demonstrate the feasibility of our concept for measuring vibration, waterborne, flow and flow induced noise with an affordable sensor which can be attached to a ship. The Phase I research will identify the types of sensors required to perform these noise measurements. The sensor configuration will be developed and will include key features such as how they will be connect ...

Silicon-based photoconductive switch technology, despite its widespread industrial use, has not reached its limit in repetition-rate nor recovery-time. While traditional Si-PCSS systems have demonstrated poor recovery time (tens to hundreds of microseconds), new understanding in absolute photo-carrier generation and the resultant reduced sweepout time, provides one means to get beyond this seeming ...
