Phase II will utilize knowledge gained from phase I work to develop and execute a manufacturing process suitable for producing quantities of 3-D printed discrete circuits for radiation detection systems.  The goal is to support mobile radiation detection system requirements for high voltage, analog amplification, and MCA functionality to produce differential pulse height spectra in time sequence. ...

At the completion of the research and development effort a Li-foil multi-wire proportional counter (MWPC) neutron detector with more than 625-cm2 of active area will be included in a portable radiation detection system. The system is expected to outperform the standards set by the ANSI N42.53 standards, and gamma-ray rejection ratio (GRR) of 1.0x10-8 or better. A gamma-ray spectrometer for isotope ...

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 ...

The potential threat of directed energy weapons (DEW) and other high peak power electromagnetic transient signals require radar systems to implement front door protection against high power signals. Fast ultra wideband (UWB) and high power microwave (HPM) signals are not successfully blocked by most current protection technologies. The Phase I work demonstrated a quasi-passive, solid state e ...

Programs such as Airborne Laser and Space-Based Laser require highly mass efficient structures. Because of their high specific strength and stiffness this naturally leads to graphite fiber reinforced polymer (GFRP) materials for many system components. In fluid storage tank applications GFRP laminates often develop microcracking when subject to cryogenic temperatures and/or stresses due to press ...

"A drastic reduction in structural weight is an indispensable prerequisite to realize future Theater High Altitude Area Defense (THAAD) systems. Boost Defense segments of the program such as the Airborne Laser (ABL) and Space-Based Laser (SBL) require thestorage and transport of large amounts of cryogens. All elements contributing to the cryogenic system mass must be as light as possible. Advanc ...

Programs such as Airborne Laser and Space-Based Laser are in need of highly mass efficient structural materials to achieve system performance targets. This naturally leads to graphite fiber reinforced polymers for many system components. For someapplications, such as cryogen storage vessels, these materials are subject to micro cracking under little or no structural loading. New materials with ...

Backplanes are key building blocks around which larger electronic systems are often implemented. They are designed so that the insertion of application derived function boards can use backplane paths for board-to-board communication. As systems grow, requiring more, higher-bandwidth paths, electronic backplanes are becoming inadequate and, for example, pin limitations have become a severe design c ...

Recent advances in directed energy weapons (DEW) require radar systems to implement front door protection against high power signals. Although nonlinear protection elements have been successfully employed in the past, fast ultra wideband (UWB) and high power microwave (HPM) signals are not successfully blocked by most current circuit protection technologies. This proposal details the develop ...
