Resumen:
In this work the experimental assembly and the electrical characteristics of a plasma curtain discharge with a cylindrical geometry is presented. The discharge is generated at atmospheric pressure, combining a dielectric barrier discharge (DBD) with a corona discharge (CD). The DBD is established between two aluminum ring-shape electrodes separated by a circular dielectric plate and the CD discharge is generated with a third electrode consisting in a cylindrical mesh positioned coaxially respect to the DBD electrodes. The DBD electrodes and the CD electrode are separated by an air-gap. The discharge consists in a train of streamers crossing the air-gap. A study of the electrical characteristics of the discharge has been performed and the range of applied voltages for which the discharge remains stable and uniform is determined. Also, a stacked arrangement was studied by placing a second set of DBD electrodes parallel to the first one, along the CD electrode axis. It was found that in this parallel configuration the discharge is established properly, showing that an extended stacked configuration can be achieved without difficulty. This result is especially important for gas processing applications in which a gas to be treated flows through the discharge.
