Spectrokinetic characteristics of light emission from pentaerythritol tetranitrate single crystals detonating under the action of a high-current electron beam

The spectrokinetic characteristics of light emission from pentaerythritol tetranitrate exposed to an electron beam pulse (0.25 MeV, 20 ns, 15 J/cm 2 ) are measured in real time. It is shown that, during the impact of an electron beam, cathodoluminescence from the sample is observed. Light emission f...

Beschreibung
Zusammenfassung:The spectrokinetic characteristics of light emission from pentaerythritol tetranitrate exposed to an electron beam pulse (0.25 MeV, 20 ns, 15 J/cm 2 ) are measured in real time. It is shown that, during the impact of an electron beam, cathodoluminescence from the sample is observed. Light emission from PETN explosion occurs on the microsecond time scale. Spectral pyrometry measurements processed in the Wien coordinates yielded a sample explosion temperature of T ≈ 3000 K.
