Experimental Research on Law of Plasma Generated by Ionization of CsNO_3 under High Temperature and High Pressure

为了验证硝酸铯(CsNO_3)在火药燃烧过程中能电离产生等离子体,设计了一套基于改进型密闭爆发器的试验测试系统。该系统根据原子发射光谱的原理,利用光谱法对等离子体有关参数进行诊断,采用控制变量的方法研究了CsNO_3电离产生等离子体的规律。试验结果表明:CsNO_3在高温高压下可以电离产生等离子体,当添加CsNO_3的质量为3 g、密闭爆发器容积为100 m L时,等离子体电子密度和温度达到最高值。

In order to verify that cesium nitrate（ CsNO3） can ionize and generate plasma during the combustion of gunpowder,a test system based on an improved closed explosive is designed. The system uses spectroscopy to diagnose the relevant of parameters of the plasma based on the principle of atomic emission spectroscopy. The experiment uses a controlled variable method to study the law of plasma generated by ionization of CsNO3. The experimental results show that CsNO3 can be ionized to produce plasma under high temperature and high pressure. When the mass of CsNO3 is 3 g and the volume of the closed explosive is 100 m L,the plasma electron density and temperature are maximum.
