Surface discharge behavior and light emission properties for the configuration with two plane electrodes on the dielectric plate with a flat cable backside electrode have been investigated. In the case of negative polarity, surface discharge developed from the HV electrode (cathode) to the grounded electrode (anode). The extension of the negative surface streamer is significantly faster than that of positive surface streamer. These results suggest that electrons with high energy are included in the negative surface streamer head and the photoemission and the secondary emission play important role in the negative streamer extension. It suggests that devices using multiple excitation such as by UV radiation and electrons with high energy from streamer should be possible.
