ABSTRACT Exploding bridgewire (EBW) detonators work by bursting a thin conducting wire as a result of a high voltage discharge. This process is known to produce a strong UV emission. The roles of optical absorption, photochemistry, shock sensitivity, and impact sensitivity are assessed with respect to the relative roles each plays in the operation of an EBW detonator. The optical absorptivity and penetration depth have been measured using dilute polycrystalline samples of PETN, RDX, HMX, CL-20 and HNS in KBr between 190 and 1100 nm. The results show strong absorption at UV wavelengths with a gradual decline at longer ones. It is found that while strong UV absorption appears to be necessary, it is not sufficient to make an effective EBW detonator.

多晶 PETN、RDX、HMX、CL-20 和 HNS 的光吸收及其对爆炸桥丝雷管功能的可能影响

摘要 爆炸桥线 (EBW) 雷管的工作原理是在高压放电时炸开一根细导线。众所周知，这个过程会产生强烈的紫外线辐射。光吸收、光化学、冲击敏感性和冲击敏感性的作用是根据每个在 EBW 雷管操作中所起的相对作用来评估的。使用 PETN、RDX、HMX、CL-20 和 HNS 的稀释多晶样品在 190 和 1100 nm 之间的 KBr 中测量了光吸收率和穿透深度。结果显示在紫外线波长处有很强的吸收，在较长波长处逐渐下降。研究发现，虽然强紫外线吸收似乎是必要的，但不足以制造有效的 EBW 雷管。
