GRI will develop the capability to fuse 3D map and radiation data from multiple 3D radiation mapping systems in real-time into a single, cohesive global map of an operating environment. This new capability will automatically fuse 3D map and radiation data from the GRI Localization and Mapping Platform (LAMP) systems on ground vehicles and unmanned aerial systems (UASs). This capability will be bui ...

Welkin Sciences proposes investigating scintillation-hardening techniques applicable to DoD's strategic communication systems, focusing on hardening specific SATCOM links within the Ballistic Missile Defense System Communications Network that are of particular interest to DTRA and its customer, the Missile Defense Agency (MDA). These new scintillation-hardening techniques are based on computationa ...

In the condition of a nuclear event, it is critical that warfighters and first responders are equipped with active dosimeters and dose rate meters.  These tools can be made from scintillation-based detector systems that require a high performance photodetector.  The silicon photomultiplier is a compact photodetector that would be ideal for such a detector system, yet their performance suffers fr ...

Improving the effectiveness of counter-WMD operations requires improved understanding of weapon-target interaction. Specifically, time-resolved measurements of temperature and composition are required to allow temporal evolution of a detonation fireball. To address this need, SA Photonics will develop MONITOR, a laser-based temperature diagnostic which will enable wide dynamic range temperature me ...

This program seeks to develop ultrafast, radiation hard, and rugged scintillators for nuclear battlefields based on high  melting-point temperatures oxide crystal. Doping, co-doping, and alloying schemes will be explored to reach the target of < 5ns decay time, light yield >1000 ph/MeV, moderate energy resolution

The detection of radionuclide aerosols is a critical indicator of a nuclear detonation. Current detection systems used in the Comprehensive Nuclear Test Ban Treaty’s  (CTBT) global monitoring network stations spend 24 hours collecting and concentrating particulates from the air to gather enough sample material for adequate detection sensitivity. This approach is inherently a batch process that ...

There is significant interest in multi-functional materials enabling gamma-ray spectroscopy, neutron/gamma pulse shape discrimination (PSD), ultra-fast response, and time-of-flight (TOF) neutron detection. These materials would be used in a variety of mission scenarios for the localization and monitoring of special nuclear materials. Commercial inorganic scintillators may offer some of these chara ...

The detection of radionuclide aerosols is a critical indicator of a nuclear detonation. Existing sensors as part of the International Monitoring System operate in a batch process and typically have a 48 to 72 hour delay between aerosol sample collection and measurement activities due to limits of instrument sensitivity. The continuous, instantaneous measurements of atmospheric aerosol radiation le ...

Hazard assessment tools that model the transport and dispersion of Chemical, Biological, Radiological, Nuclear and Explosive (CBRNE) materials through urban areas are only as good as the 3D models that inform the physics model. Maintaining accurate, up-to-date 3D models of urban areas is challenging. Even in the commercial world, urban construction and demolition may result in the models created a ...

The goal of this project is to develop the Semantic Analysis Technologies for the Identification of Dual Use Research of Concern (STIR) capability.  STIR processes scientific documents using semantic technologies and inference algorithms to identify potential Dual Use Research of Concern (DURC).  The focus is on 15 high consequence pathogens and toxins and 7 experimental categories that have bee ...
