Characterization & Elimination of Illicit Explosives
Thrust Leader: Jimmie Oxley, University of Rhode Island
Detection of explosives requires knowledge of the signature characteristics of various threat materials and seeks to answer the following questions:
- What makes a chemical capable of being an explosive or of detonating?
- Can we prevent terrorist acquisition and/or use of precursor chemicals to make explosives?
- Are there characteristics of terrorist-used explosives that exhibit observable signatures by current or envisioned sensor systems?
- Can we concentrate sample collection to enhance our ability to detect these signatures?
- What properties of terrorist-used explosives pertain to safe handling and creation of realistic simulants?
Activities of this research thrust include
- Characterization of signatures and properties of a variety of potential threat materials;
- Design of protocols for safe handling and disposal of these threats, including ways to prevent common chemicals from being used to make illicit explosives while still allowing their intended uses;
- Determination of surface-explosive particle interaction in order to best locate and collect explosive residue.
