摘要
研究相近碰撞速度、不同入射角度超高速碰撞产生的瞬态等离子体的电子温度随时间的变化规律.设计了瞬态等离子体诊断的扫描Langmuir探针诊断系统.通过二级轻气炮加载LY12球形铝弹丸,采用设计的扫描Langmuir探针诊断系统分别进行了入射角度(与靶板水平面的夹角)为45°,60°和90°条件下碰撞LY12铝靶产生等离子体的实验诊断.对实验得到的有效数据进行了每1/2个周期的读取和处理,获得了在整个物理过程中给定探针位置处等离子体的电子温度与碰撞角度的关系.
To investigate the variation of electron temperature of plasma generated by hypervelocity impact at close impact velocities and different incidence angles, a sweep Langmuir probe diagnostic system suitable for transient plasma diagnosis is designed. LY12 aluminum spherical projectiles are loaded by two stage light gas gun, using sweep Langmuir probe diagnostic system designed to measure plasma. The LY12 aluminum projectile impacted the LY12 aluminum target at incidence angles of 45°, 60° and 90° in a horizontal plane. Effective data obtaied from experiments at positions of probes as given in every half period. The dependence of electron temperature on impact angles during the whole physical process were obtained.
