The unique electronic properties of periodically-arranged indium arsenide/gallium antimonide (InAs/GaSb) mesas in the type-II strained layer superlattices (SLS) make them a superior alternative to the conventional HgCdTe sensors for longwave infrared focal plane array (LWIR FPA) detectors. However, despite the highly promising quantum structures of SLS, its performance is currently limited by high ...

Physical Sciences Inc. (PSI) proposes to develop an Advanced Learning-Enabled Threat Search (ALERTS) software to significantly enhance detection range and source classification accuracy during search for Special Nuclear Materials and other radioactive threats. The software will implement Machine Learning algorithms for automated extraction of spectral and temporal features by training on sets of g ...

"Increasing the distance for standoff detection of nuclear materials, beyond that capable with direct radiation detection, using alternative signatures, such as the concentration of ionization in the surrounding atmosphere, improves the ability to locate, track and monitor this material. Ionizing radiation generates free elections, ions, and exited states in the nearby atmosphere, even when the s ...

We propose to develop Prediction of Emergent SCIENce & Technology (PRESCIENT), a system that mines a text corpus of scientific patents and publications to discovers emerging technologies that may impact WMD or CWMD. PRESCIENT will take as input a diverse corpus of patents and publications, including metadata about contributing authors and organizations, and will produce as output alerts with timel ...

Neutron multiplicity can provide effective detection and identification of shielded Special Nuclear Materials (SNM) based on analysis of the time correlated neutron multiplicity distribution. RMD is developing a composite detector, consisting of Cs2LiYCl6:Ce (CLYC) scintillator incorporated into dual-mode plastics, which provides an ideal solution for this task. CLYC offers (1) efficient thermal ...

Agiltron will develop a new class of chemical vapor analyzers by leveraging Agiltrons development and production of micro-electrical-mechanical systems (MEMS) products and expertise with surface-enhanced Raman scattering (SERS) analysis and film fabrication. Our approach capitalizes on integration of these separate technologies for the first time to generate a unique and novel functionality that f ...

This Phase 2 project will further develop and scale a manufacturing process for the production of 5-25 kilogram quantities of encapsulated HI3O8 with a particle size of approximately 2 m and other sizes as desired by the sponsor. This project addresses the need to develop manufacturing processes and build a production capability for the manufacture of HI3O8 a halogen-containing chemical reagent f ...

Physical Sciences Inc. (PSI) proposes to utilize a ground-based simulation facility based upon its patented FAST technology to obtain critical data necessary to validate and extend the capabilities of the MDAs high altitude plume code: SOCRATES-P. Far-field plume signatures arise from the hyperthermal interaction of rocket plume effluent with the atmosphere at altitudes greater than 100 km. In P ...

The modeling & simulation (M&S) tools currently used by the Missile Defense Agency (MDA) to simulate radiofrequency (RF) propagation effects on ballistic missile defense (BMD) radar performance produce medium-to-high fidelity results. However, these tools do not incorporate all relevant RF propagation phenomena, assess propagation effects on radar system performance, or support real-time simulatio ...
