摘要

摘要提出了一种用于低温非稳态大气等离子体射流微波诊断的系统，其工作原理基于对圆柱形微波腔谐振器电型主模品质因数变化的记录。测量了氦气流中阻挡放电等离子体射流平均体积电导率的时间相关性。放电由频率为 9 kHz 的交流电压源供电。如此低频率的电源电压使得分辨阻挡放电的单个击穿脉冲成为可能。

Microwave Diagnostic Complex for Cold Atmospheric Plasma Jets

A system for microwave diagnostics of low-temperature non-stationary atmospheric plasma jets is proposed, the principle of operation of which is based on the registration of changing in the quality factor of the main mode of the electric type of a cylindrical microwave cavity resonator. The time dependences of the average volumetric conductivity of a plasma jet of a barrier discharge in a helium flow are measured. The discharge was powered from an alternating voltage source with a frequency of 9 kHz. Such a low frequency of the supply voltage made it possible to distinguish individual pulses of breakdowns of the barrier discharge.
