Abstract :
We present images of atmospheric pressure glow discharges (APGD) in pure noble gases, helium and argon, for a needle-plane (N-P) electrode geometry. The images have been obtained using an intensified charge-coupled device (ICCD) digital camera, at nanosecond exposure times. We present time-dependence of discharge images perpendicular and parallel to the interelectrode gap for both helium and argon.
