متن کاملNondestructive Identification of Chemical Warfare Agents and Explosives by Neutron Gnerator Driven Pgnaa
Prompt gamma-ray neutron activation analysis (PGNAA) is now a proven method for the identification of chemical warfare agents and explosives in military projectiles and storage containers. Idaho National Laboratory is developing a next-generation PGNAA instrument based on the new Ortec Detective mechanically-cooled HPGe detector and a neutron generator. In this paper we review PGNAA analysis of...
متن کاملResearch and Development of High-performance Explosives
Developmental testing of high explosives for military applications involves small-scale formulation, safety testing, and finally detonation performance tests to verify theoretical calculations. small-scale For newly developed formulations, the process begins with small-scale mixes, thermal testing, and impact and friction sensitivity. Only then do subsequent larger scale formulations proceed to...
متن کاملNon-proximate detection of explosives and chemical warfare agent simulants by desorption electrospray ionization mass spectrometry.
Desorption electrospray ionization (DESI) mass spectrometry is used for the selective and sensitive detection of trace amounts of explosives and chemical warfare agent simulants from ambient surfaces at distances of up to 3 meters from the mass spectrometer.
متن کاملHigh-temperature Explosives for Insensitive-munitions Applications
We are developing new energetic structures expected to have superior insensitivity characteristics and superior performance characteristics relative to currently used insensitive high explosives. The chemical structures proposed herein are a series of zeroto low-hydrogen-content, polynitro, polycyclic heteroaromatic compounds based on novel nitrogenous heterocycles. By analogy to other nitrated...
