 | Raman-based spectroscopy is potentially militarily useful for standoff detection of high explosives. Normal (nonresonance) and resonance Raman spectroscopies are both light scattering techniques that use a laser to measure the vibrational spectrum of a sample. In resonance Raman, the laser is tuned to match the wavelength of a strong electronic absorbance in the molecule of interest, whereas, in normal Raman the laser is not tuned to any strong electronic absorbance ... |

| A critical Army mission is to improve predictive technologies for the development of future weapon systems. Shear initiated reactions are an important aspect of lethality, survivability, and vulnerability considerations, i.e., the increased lethal effects due to shear localization of reactive materials, reactive armor applications, and shear-induced reactions in munitions due to fragment impact. Present computational capabilities in continuum mechanics codes used by Army designers do not possess the capability to ... |

| One consequence of the development, testing, and firing of ammunition is the potential contamination of test sites by high explosives, propellants, and pyrotechnics. These energetic compounds pose particular environmental concerns because of their unusual chemical, physical, and toxicological properties. For this reason there is a need to scrutinize past and current defense activities to ensure that they have had no adverse effect upon the surrounding environment. The need for environmentally ... |

| A method of analysis for nitroglycerine (NG) in soil and on the surfaces of mortar fins (a common range scrap material) was developed using a field-portable gas chromatograph system. The method combines quick and simple sample preparation procedures with a rapid gas chromatographic (GC) analysis using a thermionic ionization detector (TID) that is selective for compounds containing nitro (NO2) functional groups. Very good agreement was observed among NG values established ... |

| Munitions use on military lands is of keen environmental interest primarily due to the potential for contamination from unexploded ordnance (UXO) constituents, Explosive fillers such as Trinitrotoluene (TNT), Royal Demolition Explosive (RDX), and High Melting Explosive(HMX) are subject to environmental fate and transport congruent with the ecological setting into which they are released, Key environmental processes are dissolution, adsorption and chelation processes and biological action, The expected soil component responses ... |

| The Strategic Targets Project Office, within the Ballistic Missile Targets Joint Project Office of the U.S. Army Space and Missile Defense Command, proposes to use vanous configurations of a seedant (deuterium fluoride), high explosive, and sensor instrumentation payload package on several target missile launches from Vandenberg Air Force Base (AFB) to independently verify Ground- based Midcourse Defense Element interceptor effectiveness. The proposed action consists of three main activities. The first ... |
