Abstract

Glowing spectra of products resulted by heavy metal azides explosive decomposition initiated by high-current electron beam were measured and identified. Intensive emission lines related to atoms of alkali metals were observed in spectra of samples under study. These atoms enter explosives during their preparation. Emission lines of elements being part of a sample holder were also presented in spectra of explosion.

Highlights

  • Pulsed optical spectroscopy with the high time resolution is one of the promising and modern methods for studying of explosive decomposition of energetic materials (EM) [1,2,3,4]

  • It can be seen that two types of glowing can be observed in spectrum of explosion. These are line spectra of atoms being a part of explosive material and a continuous spectrum representing glowing of dense low-temperature plasma

  • Plasma pressure and temperature grow at the deceleration of explosion products on a solid obstacle and this leads to broadening of spectral lines of atoms being a part of explosive It has been established that intensity ratio of continuous and line emission in spectra of explosion plasma depends on a mass of a sample and expansion conditions of explosive decomposition products

Summary

Introduction

Pulsed optical spectroscopy with the high time resolution is one of the promising and modern methods for studying of explosive decomposition of energetic materials (EM) [1,2,3,4]. The presented work is aimed at measuring of emission spectra observed during explosive decomposition of heavy metal azides (HMA) in the spectral range of 200–980 nm with high spectral resolution sufficient for identification of explosion products.
