Evaluation of the electron density and temperature in a sliding discharge
A sliding discharge using two electrodes on a dielectric layer (upper electrodes) and a third electrode on its reverse side, facing the upper inter-electrode gap (lower electrode) was generated in air at atmospheric pressure. Application of a high dc negative voltage to one of the upper electrodes a...

A sliding discharge using two electrodes on a dielectric layer (upper electrodes) and a third electrode on its reverse side, facing the upper inter-electrode gap (lower electrode) was generated in air at atmospheric pressure. Application of a high dc negative voltage to one of the upper electrodes and to the lower electrode, and a high ac voltage to the other upper electrode generates a stable and homogeneous surface plasma (plasma sheet) in the upper electrode's gap. In this work, the plasma sheet optical emission of the spectral bands corresponding to the 0-0 transition of the second positive system of N 2(λ=337.1 nm) and the first negative system of N 2 +(λ=391.4 nm) has been measured and analysed. It was found that the plasma sheet consisted of a set of cathode-directed streamers. The streamer generation frequency and its transit time across the inter-electrode gap have been studied.
