SpletSPARK FORMATION IN AIR When considering spark formation in spark gap detonators and in pin-to-case electrostatic discharges the tendency is to assume that only one spark is formed. However, evidence of multiple sparks has been observed in X-ray CT images of detonators which failed to initiate following pin-to-case electrostatic discharges [2]. SpletAbstract: Qualitative and quantitative studies of the oxidation of polycrystalline copper (Cu) thin films upon exposure to ambient air conditions for long periods (on the order of several months) are reported in this work.
