摘要: Novel sensors have been developed to measure the time resolved position and thickness of conducting zone detonation waves in columns explosive. The employ phenomenon capacitive coupling distinguish between reaction zone, unreacted explosive products based on change conductivity. An electrode is driven with a square-wave alternating voltage, which induces stronger displacement current than elsewhere. size effect then inferred by measuring relaxation circuit. Unlike some other electromagnetic sensors, these are not embedded within material, but instead designed be positioned outer surface. This paper describes design an initial test. A fibre-coupled laser flyer system has built perform initiation experiments.
