Excitation of PETN-charges with safe light-sensitive pyrotechnical compositions initiated by incoherent light pulse sources

摘要

An ongoing research programme at Russian Federal Nuclear Centre is devoted to numerical and experimental studies of safe HE excitation by incoherent light pulses. The paper describes the main obtained results including experimental set-up, construction of high-voltage spark pulsed light sources, construction of optical detonators with a power-intensive compound, critical parameters of initiation energy and radiant power density. The experimental results obtained at initialing detonation in HE devices with compact incoherent pulse light sources are presented. An application of this method for high-speed photorecording is discussed.
