摘要

爆炸薄膜具有多种潜在的应用，包括电流中断、高能材料的点火和强光源。然而，这些事件的特征仍然是一个挑战，因为在我们的研究中，一个事件的平均持续时间只有100毫秒左右。对爆炸薄膜和等离子体产生现象的全面了解正在进行中。本文研究了金属化聚丙烯薄膜样品上爆炸膜事件的光谱和电输出。假设爆炸膜产生的等离子体是黑体辐射体，可以利用波长与强度的趋势来估计峰值温度。这些数据使我们能够更准确地描述由爆炸膜产生的等离子体。对等离子体的确定性机制的全面理解使爆炸膜应用的未来可控性和可调性成为可能。

Characterization of Exploding Film Plasmas Using Emission Spectroscopy

Exploding films have a variety of potential applications including current interrupters, ignition of energetic materials, and sources of intense light. However, characterization of these events remains a challenge as the average duration of an event is only on the order of 100 mus in our studies. An effort to obtain a complete understanding of the exploding film and plasma generation phenomena is underway. This paper investigates the spectral and electrical output of exploding film events on metallized polypropylene film samples. Assuming the plasma generated from the exploding film is a blackbody radiator, peak temperature can be estimated using trends of wavelength versus intensity. This data allows for a more accurate characterization of the plasma that results from the exploding films. A holistic understanding of the deterministic mechanisms of the plasma enables future controllability and tunability in exploding film applications.
