Observation of stepped creation of oscillatory luminous beads in chain of air plasma

الملخص EN

Cathode-directed electrical discharge in air at 100 torr, advancing under the influence of single modulated high voltage pulses, have been found to have the appearance of a necklace of luminous beads.

Photomultiplier studies reveal the monotonic advance of the wavefront, the oscillatory nature of the bright regions and suppressed emission from the dark spaces
