Electron temperature diagnosis of plasma generated by hypervelocity impact of a LY12 aluminum projectile into a LY12 aluminum target

摘要: 为了诊断超高速碰撞过程中产生等离子体的电子温度，进而研究不同碰撞速度、相同入射角度（弹道与靶板平面的夹角）下超高速碰撞产生瞬态等离子体在整个物理过程的电子温度随时间的演化规律，设计了适用于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，运用设计的扫描Langmuir探针诊断系统分别进行了入射角度为30、不同碰撞速度下碰撞LY12铝靶产生等离子体的实验诊断。获得了整个物理过程在给定探针位置处等离子体的电子温度与碰撞速度的关系。Abstract: A sweep Langmuir probe diagnostic system was designed to investigate the electron temperature evolution of plasma produced by hypervelocity impact of LY12 aluminum projectiles into LY12 aluminum targets. In the experiment, LY12 aluminum spherical projectiles were loaded by a two-stage light-gas gun, the incident angle of LY12 aluminum projectiles was 30 and the impact velocities were different. The relation between the electron temperature of plasma and the impact velocity for the whole physical process was obtained by treating the effective data, which at the given probe positions were measured by the designed diagnostic systems.
