Abstract :
Experimental results on the ignition of a number of energy-storage materials initiated with electron beam were presented. Influence of nanoscale admixtures of copper oxide powder on electron beam initiating ability was investigated. Sharply increase of electron beam initiating ability on the threshold concentration values of semiconductor admixtures was shown. Obtained effects were explained in terms of thermal percolation.
