The Defense Threat Reduction Agency (DTRA) requires microelectronics for itself and other DoD agencies that can operate reliably in the harsh environment of space. This Phase II Small Business Innovation Research (SBIR) proposal for DTRA extends the work

The Defense Threat Reduction Agency (DTRA) recognizes the need for efficient low power high bandwidth radiation hard optoelectronics for optical intereconnects; i.e. electrical-to-optical (E/O) conversion, optical-to-electrical (O/E) conversion, and low loss optical interconnects are imperative for photonic solutions to be competitive with conventional military RF components.For the development of ...

DTRA is faced with the challenge of extracting and effectively utilizing information from a very large and diverse set of natural language and structured data sources. Current methods often lack contextualization and are generally noisy, shallow, patchy, and overly low-level. We will develop a unifying, general, and elegant solution to address this challenge, based on the overall Textual Rulelog a ...

We propose the development new kind of high resolution tunable spatial heterodyne spectrometer for nuclear forensics. Preliminary results have shown that this spatial heterodyne spectrometer can be made compact without sacrificing its high resolving power for isotopic attribution of nuclear materials. Thus, the spatial heterodyne spectrometer will be able to provide the origins of nuclear material ...

Nuclear weapons effects (NWE) testing and other experiments conducted with plasma radiation sources require that test articles be exposed to radiation but protected from fast moving debris generated by a high power source event. Solid barriers or membranes are unacceptable because they attenuate the desired radiation, and physical shutters of reasonable size and complexity have difficulty reaching ...

Orora Design Technologies proposes to develop electronic design automation (EDA) tools employing minimally invasive circuit design-based methods to mitigate single event effects (SEEs) for next generation Ultra-DSM CMOS (

The objective of this proposal is to develop enabling technology for the production of bulk scintillating nanocomposites that have gamma radiation detection properties of single crystal NaI but with the manufacturability of plastic scintillators. These performance criteria may be met by developing nanoparticle polymer composites with ultra-high nanoparticle loadings. These ‘ultra-composites’ w ...

Analysis of nuclear material samples in the field has many advantages over laboratory analysis. Laboratory analyses can be slow, involve increased expense, lead to additional waste generation and disposal problems, and may introduce errors due to sample degradation or mishandling. In situ analysis mitigates all of these problems. The specific aim of this project is the development of a truly por ...
