Destruction of peroxide explosives.
Chemicals containing multiple peroxide functionalities, such as triacetone triperoxide (TATP), diacetone diperoxide (DADP), or hexamethylene triperoxide diamine (HMTD), can be explosive. They are impractical and are not used by legitimate military groups because they are shock and heat sensitive compared to military explosives. They are attractive to terrorists because synthesis is straightforw...
متن کاملA Laser-based Explosives Sensor
Trace explosives residues of CL20 (hexanitrohexazaisowurtzitane) and RDX (hexahydro-1,3,5-hexanitro-1,3,5-triazine are measured in real-time by surface laser photofragmentation-fragment detection (SPFFD) spectroscopy at ambient conditions. A 248nm laser photofragments the target residue on a substrate, and a 226-nm laser ionizes the resulting NO fragment by resonance-enhanced multiphoton ioniza...
متن کاملWideband terahertz spectroscopy of explosives
Time-domain terahertz spectroscopy (TDTS) has been shown to be a promising tool in detection of explosives and explosive related compounds. To date, TDTS for many explosives has been limited to spectral regions <3 THz. With recent improvements in emitters and sensors of THz radiation, we report the THz absorption spectra over an extended frequency band from 0.5 to 6 THz for four explosives: RDX...
متن کاملGranular Explosives and Initiation Sensitivity
Yet for numerical simulations of detonation waves in plastic binded explosives (PBX) empirical pressure dependent reaction rates, such as ``Forest fire'' or the ``Ignition and Growth'' model, are typically used. The underlying reason for this disparity between between fundamental chemical rate laws and empirical burn models is due to the fact that a PBX is a heterogeneous material consisting of...
متن کاملFiber-Optic Sensors for Explosives Detection
As one of the most enduring hot topics, explosives detection commands world-wide interest among scientists across universities and research institutes. Abundant research achievements pertaining to this subject have been r eported. Various choices of commercial and military-grade detection units are available for deployment. Yet, airport security and the continuing threat of improvised explosive...
