Effect of Rise Time for Pulsed Discharge on High Temperature

Abstract

A pulsed discharge, which is obtained by compressing and superimposing energy in a very short time, generates a non-thermal plasma over a wide area. Therefore, the gas molecules in the plasma can be activated more effectively, and charged particles, ions, and active atoms can be generated at high density. In addition, the pulsed discharge has a high sparkover voltage, and is expected to generate a stable discharge even in high temperature gas. In this study, the current characteristics and discharge stability of pulsed discharge were measured, and the pulsed rise time and discharge gap length suitable for discharge processing under high temperature conditions were investigated.
