EFFECT OF THE INITIAL TEMPERATURE ON INITIATION THRESHOLD OF PETN WITH THE INCLUSION OF ALUMINUM NANOPARTICLES WITH THE SECOND HARMONIC OF A NEODYMIUM LASER

Abstract

The results of studying the effect of the initial temperature on the threshold of explosive decomposition of PETN and PETN with inclusions of Al 0,1 % by weight at the initiation of the first and second harmonics of the laser are presented. The experimental results indicate the identity of the development processes of explosive decomposition in the initiation with the first and second harmonics of the laser with the same effective activation energy of 0.4 eV. The difference of the absolute values of the thresholds of initiation at the initiation with the first and second harmonics in the experimental conditions is due to differences in the efficiency of absorption.
