Abstract

Formation and decay of diffuse channels of a corona discharge in atmospheric pressure air when applying modulated voltage pulses to the electrode are studied. Photomultiplier tubes, a high-speed camera, and a CuBr vapor laser monitor are used to record the radiation from the corona discharge. It is shown that the radiation of diffuse corona discharge channels is time modulated, and the pulse repetition frequency is twice as high as the voltage pulse modulation frequency (∼ 290 kHz). It is also shown that the breakdowns can occur over a short distance when bending the corona discharge channel, which reduces the channel blurring.
