已经开发出一种诊断系统来获取冲击锋的空间和时间剖面。两级轻气枪用于在 4-9 km/s 的速度范围内加速撞击器。该系统由用于测量冲击器速度的法拉第型电磁传感器、用于测量冲击波速度的带有高速条纹相机的光学系统以及带有自调节事件前脉冲发生器的延迟触发系统组成。我们描述了该系统的规格和性能以及冲击锋倾斜和扭曲的数据分析技术。最后，我们获得了铜的Hugoniot数据用于系统演示。
A diagnostic system has been developed to obtain spatial and temporal profiles of shock front. A two-stage light-gas gun is used to accelerate impactors in velocity range with 4-9 km/s. The system consists of the Faraday-type electromagnetic sensors to measure impactor velocity, optical system with high-speed streak camera to measure shock-wave velocities, and the delay trigger system with self-adjustable pre-event pulse generator. We describe the specifications and performance of this system and data-analysis technique on the tilt and distortion of the shock front. Finally, we obtained the Hugoniot data of copper for system demonstration.
