“…In the 50%A sample the branched structure extends much further into the sample and ellipsoidal bubble cavities are more evident at and near the tips of the branches. The filamentary structures are similar to those grown from positive needles in liquids [8,28], where they have been attributed to the avalanche extraction of electrons from the liquid with the structure extending progressively into the sample [28]. They have also been observed from positive points in a gel [2].…”

Recent work shows that the range of morphology of anode streamers in liquid dielectric breakdown is predicted when it is represented as stochastic growth of a branching fractal tree. This model may be analogous to the critical volume model of breakdown used in gases. Assuming there is a relationship, leads to a concept of how affecting the electron production and recombination rates in a fluid can affect streamer behavior. These concepts were tested by measuring the effect on streamer behavior due to adding a commercial antistatic additive to toluene. The results were consistent with the concepts of the model but insufficient to define the limits of the model's applicability.
