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 ...

Centeye, with subcontractor support from Airgility, proposes a Phase 1 effort to develop a marsupial system in which a sUAS "mother ship" carries up to five autonomous nano air vehicles (NAVs) to an area of interest to perform a remote chemical sampling mission in a GPS-denied environment. For Phase 1, multiple concepts for addressing navigation of NAVs between the mother ship and the chemical sam ...

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.

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 ...

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 ...

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 ...
