摘　　要：针对采用氩气放电方式产生等离子体的离子引出模拟研究需求,提出一种等离子体密度及电子温度等关键特征参数的光谱测量方法。根据氩等离子体状态建立反映其粒子间动力学反应过程的粒子布居平衡模型,并通过对比分析实验测得的发射光谱获取等离子体相关特征参数信息。实验结果表明,该光谱测量方法可获取典型工况下射流区内氩等离子体的密度及电子温度等关键参数信息,为离子引出过程的模拟研究提供一种可靠和实用的等离子体参数测量手段。In this study,a spectral measurement method of key characteristic parameters,such as plasma density and electron temperature,is proposed for the ion extraction simulation study,which produces plasma through argon discharging.According to the argon plasma state,a particle population equilibrium model of kinetic reaction processes among the main particles is established.By comparing and analyzing emission spectra acquired in the experiment,information on corresponding plasma characteristic parameters can be obtained.The experimental results show that under the typical working conditions,the proposed spectral measurement method is used to obtain key parameters such as the density and electron temperature of the argon plasma in the jet region,thereby providing a reliable and practical measurement method for the simulation studies on the ion extraction process.
