Abstract: In order to find the main area where the contactor vibrates during operation, an experiment is designed to find the threshold condition for the contactor to enter the plume working condition. We confirm that when the ratio of“gas flow rate-discharge current” exceeds 10sccm/A, the contactor enter the plume working mode. In this area, the contactor will oscillate more severely, and the peak-to-peak discharge voltage generally exceeds 5V. According to FFT analysis, the cause of the discharge instability is the ionization instability when a smaller gas supply is inlet to generate more discharge current. The frequency component corresponding to this instability is about 1MHz. The more air flow rate, or the smaller discharge current can effectively suppress the occurrence of this kind of oscillation.

Key words: plasma contactor, discharge oscillation, spectrum analysis, FFT
