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 ...

Concrete has been used in construction for centuries and is a mature technology for building large structures, but the industry is conservative in embracing new technologies. Lightweight concrete structures are not currently employed for electromagnetic interference (EMI) / electromagnetic pulse (EMP) and blast protection. Creare proposes to fabricate high strength lightweight concrete by using a ...

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 ...

Infrasound measurements are used by DTRA and the DoD for nuclear test monitoring, terrorist blast forensics, battle damage assessment, and environmental monitoring. However, these long wavelength physical signals are typically recorded through single-point sensors or sparse low density arrays. As a result, the critical signals of interest are often corrupted or masked by noise or interference that ...

Infrasound and seismic measurements are used by DTRA and the DoD for nuclear test monitoring, terrorist blast forensics, battle damage assessment, and environmental monitoring. However, these long wavelength physical signals are typically recorded through single-point sensors or sparse low density arrays. As a result, the critical signals of interest are often corrupted or masked by noise or inter ...

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 ...

To address the limitations of diagnostic equipment for chemical and biological warfare agent threats, Voxtel proposes to further develop low-cost, rapid biological-threat-reporting optical nanomaterials for a tag-track-and-locate system to consistsing of five components: 1) nanocrystal nanobeacons, a series of covert threat-functionalized optical identifiers with near-infrared through short-wave i ...

The proposed SBIR research (Phase I and II) is devoted to developing a laser-based acousto-ultrasonic system for inspection of sealed containers. The system represents a promising technology for improving safety management in anti-terrorism and treaty compliance operations. The system will use a pulsed laser to excite the container and a laser Doppler vibrometer for long stand-off vibratory (ult ...

The Defense Threat Reduction Agency (DTRA) and the U.S. Strategic Command Center for Combating Weapons of Mass Destruction (SCC-WMD) requires transformational materials technology to support the intelligence, surveillance, and reconnaissance (ISR) of personnel and materials associated with weapons of mass destruction (WMD) development, manufacturing, and proliferation. Voxtel, Inc. proposes to fa ...
