The temporal development of prebreakdown currents in uniform field air gaps (around 1cm. length) is investigated. These gap currents were determined by observation of changes in potential across a resistor in series with the gap. While in previous work avalanche initiating electrons were released mainly through the use of spark gap radiation, here a short duration nitrogen laser pulse released electrons from the cathode. Although a detailed explanation is premature, a previously unreported after current was observed in the presence of a Teflon spacer. Since the air gap by itself behaved as observed by other authors using similar techniques, it appears that a valid new observation has been made.
