The goal of the proposed DTRA Phase I program is to develop a set a diagnostic tool to capture the evolution of aerosols and particulates ejected from liquid-filled containers impacted by fragments and shock waves in a detonation environment. Since these involve CWMD scenarios, the need is for optical diagnostics that are capable of providing accurate measurements at large standoff distances. Furt ...

Characterization of liquid aerosol droplets in agent defeat scenarios presents enormous challenges, in part due to high optical density conditions in sprays generated from shock or fragment interactions with liquid-filled containers.  We propose a new diagnostic that can probe optically dense regions, based on optical scattering of laser light from particles/droplets.  Our diagnostic instrument ...

The cybersecurity tool landscape is rapidly expanding and becoming more complex. It is becoming increasingly difficult for organizations to effectively manage all of the cybersecurity tools they utilize. This is due to the growing complexity of network environments, increasingly advanced and frequent attacks, an abundance of information being ingested from cybersecurity tools, and the demand for b ...

There is a growing need to accurately characterize nuclear materials not only for nuclear safeguards and nonproliferation treaty verification but also for forensics and provenance. At present, nuclear material identification requires samples to be collected and sent to laboratories for analysis using large and expensive equipment, such as inductively coupled plasma mass spectrometers (ICP-MS) or s ...

Spectral Labs Geiger-Müller Tube Replacement (GMTR) concept will exploit small. low-cost scintillators for a gross gamma counting sensor.  Since GMTR will require less production processing steps compared to GMTs, GMTR devices will be cost competitive to equivalent sensitivity compensated GMTs in full scale production.  The small crystal sizes projected will result in partial deposition of phot ...

Spectral Labs is proposing to continue the development of a simulation software for use with standalone COTS VR headsets which enables the accurate simulation of radiation behaviors and also the equipment used to measure such radiation for this Phase II SBIR activity. SLI will build upon its decade-long history of simulation and computer-based training for the rad/nuc mission space which will enab ...

This proposal for Phase II in response to the Defense Threat Reduction Agency (DTRA) topic 212-006 “Algorithm that can locally link radiation detectors (of different resolutions) to enhance identification/ localization capability”. The topic describes the need for an algorithm to support the fusion of multiple and varied detector outputs into actionable information. The specific focus is to id ...

The Nuclear Logistics Technical Division (NLT) maintains databases and application services pertaining to the national nuclear stockpile. The sensitivity of this data necessitates careful and close monitoring for anomalous activities that could indicate a cybersecurity threat or other deviation from the normal operating environment. Virtualitics seek to apply anomaly detection methods to event and ...

The Defense Threat Reduction Agency (DTRA) uses High-Fidelity (HF) computer codes, many of which are legacy codes that have evolved over many years, to investigate weapon effects phenomenology and techniques for countering Weapons of Mass Destruction (WMD). As DTRA’s reliance on HF codes for tasks critical to national security continues to increase, transitioning such codes from legacy coding pr ...

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 ...
