Abstract :
Summary form only given. It has been already known that many filamentary discharge channels can be observed in dielectric barrier discharge (DBD) reactors. As those filamentary discharge channels are usually not located at fixed positions, the diagnosis of such discharges is of difficulty. In this study, a single channel discharge reactor (SCDR) driven by a positive pulse power supply has been developed for the diagnosis of DBD reactors. The SCDR consists of two alumina plates and two pin electrodes. The single discharge channel can be fixed in the space between two alumina plates covered with pin electrodes. The discharge is characterized using an ultra highspeed camera to confirm the fixed discharge channel, a monochromator equipped with an ultra high-speed streak camera to measure emission lines at various discharge times, a oscilloscope of a voltage probe and two current transformers to monitor waveforms of discharge voltage and currents. A comparison of SCDR with a DBD reactor of many filamentary discharge channels is given.
