Investigations pertinent to ignition of sprayed layers of silver acetylide - silver nitrate
In order to shape the pressure pulse produced by ignition of thin sprayed layers of silver acetylide - silver nitrate due to exposure to intense thermal radiation, a better understanding of the factors controlling ignition is required. Several experimental investigations designed to reveal or evaluate the pertinent factors were undertaken, and the results of these investigations are reported here. The principal investigations measured the ignition delay time, the pressure pulse magnitude and rise time, the thermal radiative properties, the surface appearance of SASN at high magnification; and high-speed photographs were taken before, during and after the ignition process. The small and large light sources employed at the Light-Initiated High Explosive Facility at Sandia National Laboratories in Albuquerque were characterized in terms of their radiative output. The results indicate that simultaneity of ignition and peak pressure output can be improved by irradiation with higher peak absorbed fluxes and higher absorved energies per unit area. It was also found that the absorptivity of SASN was most strongly affected in the visible portions of the spectrum by exposure to ultraviolet radiation. 9 refs., 43 figs., 1 tab.
