Popis:	Experiments were performed in which confined samples of TATB were initiated by uniform and rapid energy deposition via a penetrating electron beam. The temperature and pressure were obtained in the exothermic region with a resolution of about 2 ms. Information on reaction kinetics was obtained to very high temperatures (≳1000 °C) and pressures (≳ 3000 psi). The absence of thermal gradients greatly simplifies the analysis. Values were obtained for the thermal initiation threshold, the explosion temperature, and kinetic parameters for a consistent reaction below 380 °C. An observed endothermic reaction near 390 °C was shown to be due to an impurity. Non‐Arrhenius behavior was observed at higher temperatures. A very fast rise in the reaction rate just above 400 °C is followed by a rapid fall off from extrapolated values at higher temperatures.
