Experiments were performed using a copper antenna to observe transient electric fields generated by shocked Pentaerythritol Tetranitrate (PETN), which behaves as a piezoelectric explosive. PETN pellets were shocked using a detonator and polyvinyl chloride (PVC) as shock attenuation. The amount of attenuation was varied until an initiation threshold was found to increase the probability of a deflagration-to-detonation (DDT) transition occurring. These experiments showed distinct transient shifts in frequency over the duration of the experiments. Correlation was observed between certain shifts in frequency and if the PETN pellet detonated.
