Abstract

The atmospheric-pressure cold plasma jet that is a flowing afterglow of the interelectrode microwave discharge in Ar was investigated using various diagnostic techniques. Waveguide-type 2.45-GHz-plasmatron with the external 6-rod-electrode plasma torch was used as the cold plasma source. High-speed shadowgraphy was used to obtain spatio-temporal structure of the cold plasma jet. The periodic character of plasma generation was studied using electric probe floating potential measurements with an oscilloscope.

基于常压微波放电产生的冷等离子体射流诊断的若干技术

摘要

使用各种诊断技术研究了大气压冷等离子体射流，它是 Ar 中电极间微波放电的流动余辉。具有外部 6 杆电极等离子炬的波导型 2.45 GHz 等离子管用作冷等离子源。高速阴影成像用于获取冷等离子体射流的时空结构。使用示波器电探针浮动电位测量研究了等离子体生成的周期性特征。
