There are good reasons why plasmons might make good probes for diagnosing shock and detonation fronts. Foremost is the fact that their frequencies (10[SUP16] Hz) are higher than other frequencies in solids so they can probe very fast phenomena. Also, they are consist of collective oscillations of the valence electrons so they exist for all solids. There are at least two methods for determining plasmon frequencies. Since the frequencies (energies) are determined primarily by the volumetric valence electron densities, they correlate with a variety of physical properties including bulk moduli, surface energies, band gaps, dielectric constants, and phase stabilities. Thus they can be used to determine such things as local transient pressures, shock interface energies, and explosion sensitivities.

    Archival front curvature data from two studies of nitromethane detonating in Pyrex tubes are re-read from the original films to obtain detonation wave shapes. Each data set is fit with an analytic form, for which the fitting parameters are tabulated. The wavefront fits are also plotted in normal...

    The most important advance in shock initiation experimentation has been the development and application of in-material gauges, measuring pressure or particle-velocity histories. However, the gauge records show a number of puzzling features. These include the near linear growth of particle...

    We measured the velocity of shock waves generated by the detonation of a high explosive in a stoichiometric (equimolar) mixture of Zn and S powders. The initial decrease in the velocity of the shock wave in a sample was then found to be followed by a remarkable increase in the velocity of shock...

    One century ago, in 1909, finished one of the most creative decade for the progress of shock wave and detonation understanding. In 1899, Chapman provided the basis of what is called now the Chapman-Jouguet theory. During the following years, several authors (Jouguet, Hadamard, Crussard, Duhem,...
