Study on Width of Reaction Zone of JO-9159 Explosive Using PhotoElectric Technique

摘要

The principle of photoelectric technique used in detonation reaction zone study of high explosive was presented and the widths of reaction zone of JO-9159 explosive were investigated. Chloroform is adopted as the window material and the radiation intensity history of the shock front in chloroform is recorded by four-channel instantaneous optical pyrometer. Then, the width of reaction zone is obtained by the condition of interface continuum and the phenomena of mirror deduction. It was found that the width of reaction zone of JO-9159 explosive decrease with the charge density.
