Abstract :
Streamer corona discharge was generated by applying nanosecond-pulsed voltage with many different pulse rise times. Pulsed voltage having pulse rise time of 7-40 ns was applied to a coaxial chamber consisting of a center wire, 1 mm in diameter, and an outer electrode, 20 mm in diameter, in atmospheric pressure air. Streamer propagation in the discharge was observed using a streak camera. The propagation velocity increased with a shortening rise time of the pulsed voltage.
