Abstract
ABSTRACT Triacetone triperoxide (TATP) is a notable threat due to its widespread use in improvised explosive devices (IEDs), primarily because of its straightforward synthesis and the availability of its precursors. Its extreme sensitivity to impact, friction, and heat makes it highly dangerous to handle and detect. This study focuses on innovative detection methodologies by exploring the effects of various laser beam parameters on TATP. By applying coatings with specific and known absorption coefficients, laser energy can be precisely coupled to the material, enabling controlled energy transfer without requiring prior knowledge of the substance’s composition. This approach facilitates local initiation, significantly reducing the risk of unintentional mass detonation, which is critical for safety. In our experimental setup, graphite-coated TATP samples are exposed to laser irradiation, and the process is monitored and analyzed using proton-transfer-reaction time-of-flight mass spectrometry (PTR-ToF-MS) alongside a sensitive microphone. These tools provide real-time feedback, enhancing the reliability and safety of the detection process.
