Study of Pulsed Discharge Characteristic of Methyl Iodide Mixture Gas

含碘甲烷的混合气体脉冲放电是研究放电引发的脉冲氧碘化学激光器的基础和前提保证。研究了碘甲烷的混合气体脉冲放电特性,实验发现,击穿电压和峰值电压与气体压强、电极间距和初始电压的乘积成线性关系,注入能量与气体压强、放电气体的体积及初始电能的乘积成线性关系。

Study of pulsed discharge characteristic of methyl iodide mixture gas is important for pulsed chemical oxygen iodine laser.The pulsed discharge profile of current and voltage,break voltage and peak voltage,deposited energy were studied and the trends were obtained.Break voltage and peak voltage goes linearly with product of pressure,interelectrode gap,initial voltage,and deposited energy goes linearly with product of pressure,discharge volume and initial energy deposited in the capacitance.
