摘要
研究了高功率脉冲氙灯放电过程中等离子体通道的演化规律。分析了充电电压、主脉冲脉宽及主预脉冲时间间隔等对等离子体通道的影响规律。实验过程中在脉冲氙灯接地端子附近观察到了明显的等离子体通道分叉现象。研究发现,脉冲氙灯工作环境中的电场分布对氙灯内等离子体通道的形成与演化特性将产生十分重要的影响,其决定了等离子体通道的形态。其他影响因素则通过改变放电通道的亮度、均匀度与充盈度等特征施加其影响。
The work studies the evolution characteristics of the plasma channel in high power pulsed xenon flashlamps.Various influence factors are analyzed,including the charging voltage,the main pulse width,and the time interval between the pre-ionization pulse and the main pulse.Distinct branching phenomena are observed near the grounding terminal of the flashlamps.It is found that the electric field distribution in the flashlamps＇ working environment has the most significant influence on the evolution process of the plasma channel.Moreover,the electric field distribution determines the shape of the plasma channel,while other factors influence its brightness and uniformity.
