Abstract: Temporal waveforms of pressure amplitude in various regions of a flat electrically exploded foil (EEF) have been measured. The results of measurements have been used to reconstruct the temporal evolution of spatial pressure profiles generated by the EEF. The measurements were performed using quartz pressure sensors arranged in various (central and peripheral) regions of the free surface of a dielectric substrate glued to the foil. The obtained data show that the electric explosion starts at the edges of a foil, which is followed by stronger pressure buildup in the central axial region of the EEF.
