Comparison of the Discharge Characteristics of Homogeneous Dielectric Barrier Discharge in He and Ne
摘要
Abstract
The HDBDs in 8mm gas gap distance in helium and neon at atmospheric pressure are obtained, respectively. The differences between their discharge characteristics are compared by means of voltage and current waveforms measurement, Lissajous figures measurement, and light-emission pictures taking. The change of discharge parameters of the two HDBDs with various amplitude of applied voltage are studied, and the experimental results are explained with the analysis of discharge mechanism. Results show that there are obvious differences between the dis- charge characteristics of HDBD in He and in Ne. As the amplitude of the applied voltage increases, the current of HDBD in He gas always appears as a single discharge current, and the presence of ＂residual current peak＂ is observed; the amplitude of current pulses in HDBD in He gas is higher than that of HDBD in Ne gas, and its duration is shorter. As the amplitude of the applied voltage increases, the current of HDBD in Ne gases changes from a single discharge current to multiple discharge current pulses, and the amplitude of the multiple current pulses decreases in sequence. The discharge parameters of these two HDBDs increase with the increase of the amplitude of applied voltage, but the changing trends are different.关键词
