Abstract :
We report the measurement of two-dimensional line integrated electron density profiles in a spark plasma by using Michelson interferometer in a single shot. The plasma duration is measured with beam deflection technique. Comparison of duration of plasma and current pulse indicate the existence of after glow region in such pulsed discharges.
