Explosion initiation of furazanotetrazine dioxide by a high-current electron beam

Abstract

Results of investigations of physicochemical processes which develop in furazanotetrazine dioxide under irradiation by a high current electron beam with an energy density varied in a range of 0.05-0.3 J/cm 2 are represented. The spectral kinetic characteristics of pulse cathodoluminescence are measured, and thresholds of the mechanical failure and explosive decomposition of samples are determined. A strong effect of the energy density of the electron beam on kinetics of the explosive transformation (induction period and duration of explosive glow) is revealed. The dimensional effect of the explosion initiation is found.

Ignition of organic explosives by an electron beam

“…Here is the density of the medium, measured in g/cm 3 ; e 0 = E 0 /mc 2 (mc 2 is the rest energy of an electron, equal to 511 keV); constants…”

“…Recently there has been a considerable increase in the number of papers on both experimental studies and numerical simulation of the conditions of explosive initiation by electron pulse [1][2][3][4][5][6]. It is caused by both the development of the new explosive initiation methods and scientific interest in defining the initiation mechanism in order to regulate the threshold energy of initiation purposefully.…”
